yes it's possible te iRS made a mistake. however, now the IRS reords show it paid you and will be looking for it when you file. just omitting it won't work. the IRS will recompute your taxes and reduce your refund accordingly or send you a bill. you need to contact the IRS and speak to an agent. maybe it did send you this payment espcially if it took it too long to timely refund your 2021 overpayment but the check got lost in the mail.
