Hae not got my refund

Did you efile?  Was it Accepted?  You can 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?

You did not say if you e-filed or mailed it in an envelope.  If you e-filed, was it accepted:

If you mailed it--did you use a mailing service to track it so you know the IRS received it?

When you e-file your federal return you will receive two emails from TurboTax.  The first one will say that your return was submitted.  The second email will tell you if your federal return was accepted or rejected.  If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.

First, check your e-file status to see if your return was accepted:

If the IRS accepted it, what does it say here? 

https://www.irs.gov/refunds           Or does your account say “Ready to Mail?”
