After you file

@jason_07 TurboTax gets no information from the IRS after you file your tax return. TurboTax only tells you that your e-file was "accepted."  TT never uses the word "approved" for your refund.  Approval only comes from the IRS.

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.

 TT would not know anything about any changes the IRS made to your refund or why they are sending you a letter.   This is between you and the IRS.   It is possible ---but no one at TT knows--- that you made some sort of mistake and the IRS is taking a closer look at your return.   Only the IRS can tell you.  TT cannot find out.

Call the IRS: 1-800-829-1040 hours 7 AM - 7 PM local time Monday-Friday
When calling the IRS do NOT choose the first option re: "Refund", or it will send you to an automated phone line.
So after first choosing your language, then do NOT choose Option 1 (refund info). Choose option 2 for "personal income tax" instead.
Then press 1 for "form, tax history, or payment".
Then press 3 "for all other questions."
Then press 2 "for all other questions."
- When it asks you to enter your SSN or EIN to access your account information, don't enter anything.
- After it asks twice, you will get another menu.

Press 2 for personal or individual tax questions.
Then press 3 for all other inquiries
It should then transfer you to an agent.

Remember that the “”5 day early” date is based on the date given to you on the IRS refund site—-not the date the TT site shows in your account.   If your refund does not come in five days ahead of the IRS date, they are supposed to cancel the $25 fee.

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:
