Are you still waiting for your 2019 Refund? If you efiled, Was it Accepted? Maybe you didn't finish filing it or it Rejected. 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 when you efile you get back 2 emails. The first email only confirms the transmission. The second email says if the IRS (or state) Accepte.d or Rejected your efile. Check back though your emails if you have them.
If you didn't finish Efiling or it rejected you have to print and mail prior returns now.
Then only the IRS can tell you.
