I had the same problem today. A Turbo tax representative was NOT helpful and suggested redoing my taxes even though I already paid for services. The problem I found, was in the state return. There were 1 or 2 State tax forms that were not supported for efiling. I went back to filing and clicked that I was not ready to file the state taxes. Then I was able to efile my federal taxes with no problem. Will probably need to mail the state forms. Such aggravation. Turbo Tax should have known this would be an issue and let people know before hand.
