I already filed my fed tax through turbotax and already received my refund. Now, I can't e-file my state tax because it says that "We could not e-file your return for the following reason: Duplicate Social Security Number: A tax return with the same Social Security number has already been submitted - in other words, it appears you're trying to e-file the same return twice..." since I already filed my fed tax separate from NC state tax. Anyone can help?
