Thank you for the quick response and suggestion! I did check for updates and installed 3 new Windows updates, and rebooted, and checked for updates again and it said it was up to date, and I rebooted 2 more times, but that did not resolve the problem. I have not had an issue like this in the past. Even last week I was able to bring up 2020 version "what ifs" as well as the 2020 return that had been filed, and also bring up a return in progress with TT 2021 also.
When clicking to Begin New Return in TT 2021 it does show "Good News! We Found Your Tax Info and buttons next to each to "Transfer Return" However I had already Transferred in the past and edited with new information since then.
The same happens when starting TT2020, that is, it shows the option to transfer returns from the past.
However neither version brings up any existing returns, which TurboTax has done in the past.
(By the way, yes they have always been saved on C drive after editing return with any changes.)
What could be other suggestions to determine why returns no longer display, and how to correct?
