You do not mention how long ago you mailed your tax return in. Allow at least three to four weeks for a human to open the envelope and enter your information into the system, then you can track it on the IRS refund site.
Going forward it is always a good idea to use a mailing service like certified mail when you mail in your tax returns so that you will get confirmation that it was received.
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:
