all system upgrades come with message that is damaged and unable to install

I am trying to upgrade my 2013 Mac Pro with operating system Sierra 10.12.6, to anything higher. Every thing I attempt thought App Store comes with a message: "This copy of the Install macOS (name) application is damaged, and can't be used install macOS.

I've tried High Sierra, Mohave and Catalina. The only reason I was doing this was to run TurboTax

Thoughts?
