I had same issues on new laptop, I had to change resolution back and forth to get the tax done. Until when making payment for state e-file, same problems come back, can not get to payment screen. I gave up and installed on desktop PC Windows 10 version 20H2 with 27 inch monitor with same 1920x1080 resolution, I did not have any problems (did not have to do anything with screen resolutions).
I still don't understand clearly the issues and I can not say problems has been resolved.
