My turbo tax says accepted and basically waiting for a payment but my IRS account still hasn’t moved at all. I never got my knowledgement letter or email either.

If your Turbo Tax account says Accepted that’s all the notice or email you get.   The IRS doesn’t update Turbo Tax about your return.   Turbo Tax just gives you an estimated date of 21 days to get your refund.

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.  And check your spam folder for them.

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?

If your return was Accepted or you mailed it, then check IRS Where's my refund
