Were you previously able to use the "Where's My Refund" tool to check your status and find information, but can't now? i.e., did it recognize your information previously, but now won't? The IRS does maintenance every week, and perhaps you got caught up in that. That tool can be squirrely at times as a return moves through processing and information can sometimes come and go.
The IRS says "the WMR system is not available every Monday from 12:00 am (Midnight) to 3:00 am Eastern Time. "
If you efiled your return, be sure it was accepted. If you used Online TurboTax, you can log into your Online account and check the efile status at the Tax Home to be sure it shows "accepted."
When the tool is functional again, be sure you are entering correct info--SSN, filing status, and Federal refund amount. Be sure you are using only the Federal refund amount and not a total refund amount that includes a state refund. The amount to use for the Federal refund is on your Federal Form 1040, Line 21a.
