Do you mean the state Refund?
Was your state return Accepted? Or did you mail it? 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. Just paying the fee doesn't file the return. After you paid did you continue on to the very end and hit the big orange Transmit Returns Now button?
When you log into your account you should see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. what does it say?
