Hello. I had the same issue with TurboTax Premier 2020 for Mac. I spent an hour on the phone with 2 different support reps (two because the first one was neither helpful or knowledgeable). I was told that because a copy of the federal return is required for some state returns (in my case it was Oregon), you can’t e-File federal and state separately. They must be e-Filed together.
I pointed out repeatedly too the support reps that the the software provided no instructions around this topic and it appeared to be an error that the program wasn’t allowing the state e-File as I had experienced in previous years. When they had no further advice, I requested and received a refund for the extra state download.
Just FYI. I believe this is a programming bug and hope TT corrects it for next tax season. (Or at least makes the software prompts more descriptive to explain the filing limitation.). Good luck everyone.
