My son forgot to say I was claiming him on his taxes and got his refund. When I try to file mine, it was rejected becuse he did not put himself as a dependent. Now, I owe Money which i already paid throug the IRS. If I remove him and file, I have to pay more and the payment will change. If he amend it , will it affect his refund? What is the best advice that you can give me? If i mail it, what will happen to the money I paid since there is not tax return? Thank you
