Several have suggested that you should un-install and then re-install TurboTax and its related files. Another post (above) list the items to un-install. I have done this and still no luck. This is all using TurboTax under Big Sur.
Un-installed Turbotax and re-installed. This time I got to the message where you have to select “I Agree” to the License. Then the message in a box came up stating “It may be that your internet service is down ... .” I had done the re-install using the internet, so it is not down. Then I select the OK at the bottom of that message.
Then I only get the blank box with TurboTax 2020 at the top - center, and Cancel at the bottom right, and a blue dot in the center. All menu items are dim, i.e. not selectable.
I selected Cancel at the bottom right and it stoped TT. Then re-start and the message just comes up again. Viscous Cycle.
Big Sur is giving a number of other problems, such as Safari not working correctly.
I have been using TT since Mac-in-Tax, and and Macs since before the Fat Mac. I have never seen anything as bad as this OS before.
My opinion is it is a Big Sur Problem.
