Did you efile or mail your return? They just started processing mailed returns that have been stacking up. See this IRS page for the latest information

If you efiled....Was your return Accepted? First double check your efile status here

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.

Then only the IRS can tell you. IRS Where's my refund https://www.irs.gov/refunds/
Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end. That was for federal and state combined.

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?

When will you get your refund,

Don't despair.  I sent my 2019 tax return to IRS on 2/27/2020 by mail and finally on 10/23/2020 I got my check deposited into my account.  I had sent it registered via the USPS so I could verify they received it.  However, my return was one of the thousands that got held up do to the Covid virus and lay offs of Federal employees.  So hopefully yours wil arrive soon if it hasn't already.    cvr.cbay
