I have had the same problem. I tried calling Turbo Tax and was on the phone for over an hour. They escalated the issue and I still had no resolution. I tried the 2020 solution found on your site. I tried rebooting. I tried uninstalling and reinstalling Turbo Tax. I tried rebooting in Selective Startup. I am using the same computer (Dell PC, Windows 10) that I have used for the last 3 years and have never had this issue. Not that it should matter, but I bought TT through Amazon. There has to be a resolution!
