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.
When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc. What does it say?
Then the IRS is taking a long time to process returns this year. Like over 6 months, maybe over 10 months. have you checked at IRS Where’s My Refund
