Thanks. I did that. My Amazon TT 2020 code gave an "oops...there's a problem" error. So, for kicks I put in my Amazon TT 2019 code and it worked. But it only gave me my "amazon Turbotax 2019" product in the list and the download version was the original.
So, basically, my Mac running 11.1 (Big Sur) is unable to run 2018, 2019 or 2020 (all installed) now.
I uninstalled them all, cleaned everything from ~/Library and installed just the 2019 version direct from Intuit in my products (the Amazon version) and it still failed. I have no 3rd party Malware or Virus tools installed.
Drop back and punted to a Parallels image of Mac OS 10.15 (Catalina) and am able to use TT 2020 no issue. A bit of a pain to fire up a VM just to do my taxes, but it will have to do until Intuit gets their S**t together.
