Get your taxes done using TurboTax

For me, this was resolved via "Run as Administrator." Instead of just clicking the TurboTax icon (in Windows), right-click on the icon and choose "Run as Administrator." I don't know why, but this made the problem go away for me--the W2 dialog screen appeared, and I generally have not had problems since then with TurboTax Home and Business 2021. It is probably worth a try.
