Tax return

How long has it been since you filed?   Did you efile, or did you print, sign, and mail the return?

If you efiled, double-check with this tool to be sure the return was efiled successfully and accepted:

If that showed it was accepted (or if you mailed the return), what do you see at the IRS website below for the status of your Federal refund?
https://www.irs.gov/Refunds
NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund. The amount to use is on your Federal Form 1040, Line 20a.

If that IRS tool shows that the refund has been sent, report back for more info.

If the IRS tool says it is "still being processed", and if it's been longer than 21 days, we can tell you how to speak to a live agent at the IRS to see if they can tell you anything about the delay.

Do you mean your Refund? Was your return 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?
