My 1099-MISC forms were rejected as well, telling me that non-employee compensation is supposed to be on 1099-NEC. However, my forms only had royalties, which (like rent) still go on 1099-MISC. I guess I'll wait a few days before resubmitting, to see if the IRS gets its act together by then. I'll file manually if they aren't accepted by the end of the month.
