I called Turbo Tax help and was able to resolve the error.
You have to allow an app to the controlled folder access. THIS IS ONLY IF YOU ARE WINDOWS DEFENDER (NOT A 3RD PARTY ANTI-VIRUS - like McAffee or Norton)
1. Windows Security App (search for this in the Windows 10 search box or windows tray)
2. Virus & threat protection settings (click on manage settings)
3. Controlled Folder Access
4. Allow an app through Controlled folder access (click on this)
5. + Add an allowed app (it is a box - click on this)
6. Recently blocked apps (it is a box - click on this)
7. Select Turbo Tax (a plus sign to the left)
Viola - Problem solved! Now you can save to any folder you choose.
5.
