I had the same problem on my laptop from a downloaded TurboTax Deluxe 2020 and tried what seemed to be such a ridiculous recommended fix from this website but it worked: 1) Change your screen resolution to 800 X 600 (REMEMBER what it was before so that you can set it back after you finish). Have your 16 digit license code handy in case you are asked for it. 2) Launch TurboTax 2020. Hopefully, it will work.
