I efiled my federal tax return before I finished my state income tax return (NC). I later finished my state tax return and then went to efiling. I don't know if there was some box to check I didn't see, but it acknowledged that my federal return had already be efiled and was accepted by the IRS. I had to sign into Intuit and pay $25 to efile the state tax return (I had already used my one free state return for a family member) and then clicked to transmit the state return. Now it says they AGAIN efiled my federal return. I have no idea if this messes me up with the IRS or if they will just ignore or reject the second federal return transmitted. And I don't know what I did for Turbo Tax to send it in again when it clearly said it was filed and accepted on the efile page. I wasn't worried about TT doing it TWICE
