I just got through to customer service (very frustrating but finally got a person) MY problem was that it seems there's an error within the turbo tax spreadsheet itself and the formula for one of the fields was wrong, so the addition was wrong. The agent helped me manually override and FIX that number. Hopefully, that will allow the return to go through. If not, I'll print it and mail it in now that I know it's correct for sure.
