I forgot the most important question: did you start and run the engine for a minite or so (to check for leaks) before checking the level on the dipstick? The level in the pan will be too high until the engine pumps oil into the new filter.

Traveled for 10-15 miles to warm the engine before draining, put up on ramps at the bottom of my driveway so car ended up more or less level, let the oil drain until only a couple of drops were coming out, removed the filter and installed new element. Filled with oil, ran the engine for 30 seconds, shut down and checked for leaks, let sit for 5-10 minutes then checked the dipstick. Looked a little high so I figured it was not level enough. Checked a couple of times later in the day when the car was parked in different places, each time the level was above the upper mark. I decided to take out some oil through the dipstick tube until at the upper mark. I'll watch it and when the oil gets a little darker (very hard to read now because it's almost totally clear) I may have to add some oil.
I was wondering (being paranoid) if I did something wrong with the filter change that prevented the oil from getting into the filter but I can't think what I could have done wrong.

mem4:
While I am not absolutely sure, I did change the oil in my 02 Avalon last week. Usually only during the winter time, I put in synthetic 0W-30, for reasons we are on the Canadian border and just east of one of the Great Lakes.
Although I am not familar too much with the new engine, it could be one of three things.
1. What does the manual say about oil/filter change volume? Sometime this is less than the entire capacity of the system.
2. I know on my older Avalon, the oil drain plug is faced oblique to the surface of the tank, I believe. If yours is the same, then putting it perfectly level would leave a little residual in the bottom of the pan.
3. Did you let it drain for an appropriate amount of time?? I usually walk away from the vehicle for 5 minutes or so and let it drain.
Check and try these. Hopefully, they put the oil filter in a better place than right under the manifold as they did in the older models.

You are obviously experienced and did everything "by the book". The only possibilities I can envision are a miscalibrated dipstick or the front end of the oil pan was not higher than the rear. It can be hard to judge "levelness" when standing in a slope. You lose your frame of reference.
Unless you stuffed an old sock in the center support tube, I also can see no possibility that your oil filter is not filling. In your Avalon, the oil filter is in series with the engine, so a restricted filter means less oil flow. The the oil filter was not passing any oil through it, you would hears lots of engine noises.
In the "old days", some cars had bypass valves that routed oil around the filter if it became clogged. Your engine has a bypass valve built into the oil pump to regulate pressure. It returns the oil directly back to the pan when oil pressure becomes too high.

Thanks for all the replies and advice. In thinking about it, I may have had the car too level when draining the pan. The plug is not directly out the bottom but does face back and at a slight angle. Next time I will have the front of the car higher than the back to see if this makes a difference. I may have left 8-10 ounces in the pan which would explain the slight overfill putting in 6.4 quarts.
I'm still not convinced the removal of the center filter drain and using the plastic adapter is worth the effort. I still got oil spilling out around the edges of the filter housing when I took it off. Next time I'm thinking of skipping the whole remove the center plug, stick in the plastic spigot, drain the filter thing and just spin off the whole filter housing and let it drain into the pan. My daughters Corolla has it's filter in a similar orientation and the oil just comes out around the sides when you unscrew it. Not a big deal if you are expecting it.

Your line of thinking regarding the filter cannister drain step mirrors mine exactly. I've been wondering how much greater the spillage would be if I skipped the first step. There is certainly one way to find out.
This approach would also eliminate changing the cap sealing ring ("O" ring), which seems to be redundant anyway, as oil has to leak by the drain valve first to be present in the cap cavity.

I did notice about a teaspoon of oil came out when I removed the center cap, may have slowly leaked by the drain valve in the filter assembly. Even if a small amount of oil leaks by the drain valve it will be trapped by the center cap and O ring, I don't think it would matter if it was left in there oil change after oil change. If the center cavity eventually filled up with oil it has no place to go.

I thought so. Since I just changed it myself, that is what I would have checked per my last post. The plug is oblique to the pan, not 90 degrees so if you have the car level, ..... Just put it up on the ramps next time, drain it, walk away for 5 min., then readjust, do the filter let that drain and filler up. Sounds like you were a little too good.

I didn't watch the dealer do my first oil change and plan to try it myself at the next interval. Have a 4 post drive-on hydraulic lift in my garage and just planned use it when servicing the car. Do you think all the oil won't completely drain since car will be level on the lift (instead of front end raised somewhat)? If this is the case, then it seems like all the dealers, service shops, and quick change places are likely not succeeding in completely draining the oil either.

I suspect most, if not all, Toyota dealers use a similar lift for oil changes, and the engineers who designed the oil pan realized this.
Toyota specifies 6.9 qts to fill a dry engine, versus 6.4 quarts for an oil and oil filter change. This suggests they anticipated approximately one-half quart will remain in the engine after draining.
