Filed a tax return for client taking the fireman credit.  After filing he stated he's not (just) a fireman.  I amended it and took off that credit.  Turns out I miss understood what he meant, he might have taken it as an insult, but he is the fire cheif of that firehouse...  It was my wording when i asked him.  Can i re-amend his taxes? What do I do.. remove the original amendment removing it.. then resubmit with it.  I also have the certificate showing he is the chief.  Please help.
