As said above, it is not possible to efile state unless federal was first efiled and Accepted. So federal was efiled.

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. Check back through your emails and spam or junk folders.
If you mailed federal and also efiled it there will be 2 returns in the IRS which will delay any refund.
