I recieved a 5498 for for a trustee to trustee transfer from the receiving firm. the sending firm did not issue a 1099r

i tried to get the receiving firm to fix.  they admitted it was a trustee to trustee transfer but said its too late to fix, now it looks like i made an excess contribution,  can i report to the irs the issue with documents showing where the assets came from before i start getting notices from the irs?
