Success!
I'm guessing the problem was addressed by your #1 Answer.
"1) IF a Windows computer, any waiting or partially-installed Windows updates are known to block installation of any year's TTX program...so if you are using a Windows computer, make sure you check for any Windows updates, and reboot even if you don't find any before proceeding with anything else."
"OneDrive" was most likely still trying to "Sync" my very large MS Outlook Data File between my old and new computers.
I did an "Uninstall" of "TurboTax 2022" and deleted it's folder after my first installation attempt failed. With a clean slate, I was able to get "TurboTax 2022" installed, my state forms downloaded and TurboTax poised to file an amended 2022 Return should the IRS desire one.
Now I will take a crack at getting "TurboTax 2021" installed. I don't anticipate a need for it but, "Just In Case".
