Turbotax 2020 - Mac crashing

Hello,

 

I bought the Turbotax 2020 Deluxe + State for Mac, from Amazon, and it crashes as soon as I open it.

 

A window shows up about installing an update, then disappears.

 

I managed to get a refund, and I installed the 2019 version to see if I have the same problem and I do.

 

I don't remember if I had the issue last year, but right now I'm running Big Sur. The compatibility requirement (just noticed) are Catalina and Mojave.

 

Is this an OS issue?

 

Thank you
