@fa123 I too have been using TurboTax in one form or another since about 1989 and all with the desktop software and have never run across this type of problem.
Since this started in prior years have you uninstalled the software for each tax year since it started? I would try that and also uninstall and then re-install the 2020 software.
Something I have noticed in the last few years is I needed to run the software as an administrator since some of the pages in the program were not responsive until I did that.
Try this if you have not already -
Close the TurboTax program
Right click on the TurboTax icon
Click on Properties
Click on the Compatibility tab
Check the box Run this program as an administrator
Click on Apply and on OK
