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

Does that show it was accepted, rejected, or no result found?
Also check by logging back into your Online TurboTax account. At the Tax Home what is shown for "return status"--accepted, rejected, printed, started, ready to mail, or what?
If those methods showed the return was accepted (or if you mailed the return), what do you see at the IRS website below for the status of your Federal refund?

If your return was accepted, then you have to use that IRS tool exactly right.
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, but you never received it, report back for more info.
If the IRS tool says it is "still being processed", 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. And if necessary, how to ask the IRS Taxpayer Advocate Service for assistance.
