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 2021 Form 1040) of your federal refund to track your Federal refund:

OR——if you filed by mail, expect a long wait. It is taking the very backlogged IRS six to nine months to process mailed returns. Until a human opens your envelope and enters the data into the system, nothing will even show up on the refund site, so you will have to be very patient.
That sounds like the $1400 stimulus credit and the TT fees if you had them withheld from your federal refund. You were allowed the credit on the return or the advance but not both.
So did the IRS mail you a notice explaining why the refund was less. Check your account with the IRS to see what they changed.
Did you receive only your state refund, and not the federal refund---or vice versa?
Federal and state refunds come from completely separate entities, There is no rule as to which one will come first or how much time there will be between their arrivals.
Or....did the IRS reduce your federal refund? If they reduced your refund you will receive a letter explaining why they reduced it.
