Mac Product Update is failing - error download failed

What's up with the downloaded product update for the mac? I'm trying to load my product and it requires that I update. It gets about two thirds of the way through and dies saying Error update failed.  This is the Mac TurboTax Basic 2020.

 

I then tried Mac TurboTax Basic 2019 and that one required updating too. That one also failed about two thirds of the way through saying Error update failed.

 

What's going on?
