We filed our taxes with turbo tax and it was accepted and approved on February 7th. The estimated date to receive our return was February 28th. It has not processed.

You are confusing two words that have different meanings.   Your refund was not "approved" on the day you e-filed.  It was "accepted"----and that is not the same thing as "approved."

TurboTax gives you an estimated date for receiving your refund based on a 21 day average from your date of acceptance, but it can take longer.  “21 days”  is not a promise from TurboTax or the IRS. 

 

 

 

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

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 2023 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.
