I noticed that the aero wheel cover on the rear passenger wheel is missing on my 2021 Model 3 LR AWD. Not sure if it was stolen (why would just be one be stolen)? When I tried to buy a replacement on the Tesla website, it said the available options (pre-refresh and refresh) were not compatible with my car. How do I figure out the compatible ones? Appreciate any input.
Do you have the 18" wheels? It probably said it was incompatible because a lot of LRs have the 19" sport wheels.
If you have a 2021, you likely have the "refresh" wheel cover. There are only 2 types of aero wheel covers for the 18", no third type.

If you are worried it might be wrong, you can stop by at a service center and order one there (then you can do an immediate return if it does not fit).
Note you must pop the cover in fully (especially in the center) for it to be secure. The parts holding the spokes you can feel by hand. If you add some lube to the plastic parts where the center ring interfaces with your wheel hub, it goes in and out much easier.
