You will not believe this. I found a resolution to the blank activation screen in another support site. Changing display resolution to 800 x 600 and then starting turbo tax. Activation screen shows up. Activate and then return to the original display resolution. Worked for me with Premier 2020. Once activated I tested in the original display resolution and it works. This is unbelievable to me since 800 x 600 has not been used for years.
