Sounds like it accidentally efiled State. Don't mail it if it was efiled. Double check your efile status here

Check your emails. When you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepted or Rejected your efile. Accepted only means they accepted your return FOR Processing. Not that your return is right.
