@DaraLO and @bevanrj ,
While it is true that TurboTax Mac software is compatible with macOS Mojave 10.14 or later, including Big Sur, @bevanrj and others should be aware that the initial download of TT20, first posted in the fall of 2020, was NOT compatible with Big Sur, and it took until after New Year's for TT to fix that. So anyone who paid for and downloaded their copy of TT20 in the fall has had to delete it and all associated files from their system, and then download the latest update of TT20. Some people are still having issues after that, but many of us are now doing fine.
For you, @bevanrj , since you are just purchasing and downloading now, you should be fine.
