I mailed my tax form and still no respond

It takes about three or four weeks after mailing your return to see information on the IRS refund site.  You do not say how long ago you mailed your return.

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:

You won't receive a response. If you sent your return via certified mail, you can use the tracking number to ensure the IRS received your return.

Your refund (if you had an overpayment) should be issued in about six to eight weeks from the date IRS receives your return If you file a complete and accurate paper tax return.
