with all due respect, it would be illogical for Intuit to make an Amazon-only build. Not only illogical, but dumb business as there is no value in the additional back office/server complexity. What is much more likely is that Amazon (and the big box stores like Costco) receive an early release of T-Tax license codes, i.e., summer build. That SW was released without testing for Big Sur which was released in mid-Nov; the beta was released in June. Don't forget, that iOS is a small portion of the pc market, so the early release works fine on all non-iOS devices; it's only us Apple fans that are hindered.
I purchased T-Tax at Costco in Jan and had the same open issue with Big Sur, as it was an early release. (see earlier post: I called and the Rep tried a few things over the next 10 minutes or so and she finally just asked for my license number from the Costco purchase and then loaded a newer license into my account that I downloaded, installed and work great.)
As an aside, I have had no trouble loading 2019 or 2018 versions of T-Tax in Big Sur.
