This worked when I slowed down and carefully followed VolvoGirl's advice. You must uninstall TurboTax 2021, then reinstall TurboTax 2021, then BEFORE OPENING ANY EXISTING OR NEW TAX RETURN, you need to download any and all states from your windows/browser downloader (I already had both states showing up as .exe files and loaded them carefully one by one). Once the main TurboTax 2021 is installed, and the state .exe files run/loaded, only then can you go back and open the 2021 return. I was very happy that this finally worked. 🙂
