I e-filed back in January, but my return has still not been processed according to the irs website: Your 2024 Tax Return Is Not ProcessedIf you've already filed, ...

Once your federal return has been accepted by the IRS, only the IRS has any control.  TurboTax does not receive any updates from the IRS. Your ONLY source of information about your refund now is the IRS.

You need your filing status, your Social Security number and the exact amount  (line 35a of your 2024 Form 1040) of your federal refund to track your Federal refund:

If you chose to have your TurboTax fees deducted from your federal refund, that will take some extra time, while the third party bank handles the refund processing

Note:  “Accepted” is not the same as “approved”.  TurboTax tells you the e-file was accepted if the IRS deems that there is enough information on the return for them to take it in for processing.   Only the IRS can approve of the refund, which is a later stage of processing.  If the IRS approves your refund they will provide a date for the refund to be issued.
