My return was filed paper, certified return receipt proving it was received by someone at IRS. IRS.gov and app says our info does not match. We are owed a refund so yes, we filed late, in Dec 2021. I can be patient but I'm concerned about the error message I keep getting. I'm self employed, my husband is retired. My earnings are not properly credited to my social security account. When are they going to either 1) hire more qualified people, 2) use common sense, SIMPLFY IRS returns!!
