Does anyone know why I haven’t received my tax state tax return yet I filed in April. I went to the IRS website and they didn’t know who I was. What can I do?

The IRS won't know anything about a state return.  IRS is only federal.  

If you efiled was the state return Accepted? Maybe it rejected or you didn't finish filing.

How to check your efile status

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 only the state can tell you when you will get your refund. After Turbo Tax transmits your return they are done with their part. Track State Refund
