I am in a similar situation, on 11/5/21 mailed state taxes to (Salt Lake City, Utah) and got my refund check last week, federal went to (Ogden, Utah) sent certified mail and was received on 11/12/21 and 6 weeks later, still hasn't updated to received. It seems like the IRS website is mocking me saying "it takes up to 3 weeks to show on your account"
