Since your return was accepted by the IRS, you must prepare, print, sign and mail an amended tax return form 1040X to correct the problem. DO NOT change your original tax return until you start the amended return. If you have already changed it from the way it was originally filed and accepted, you must change it back before you start the amended return.  Here is an FAQ to help you:

An amended return cannot be efiled. You must print and mail it yourself. TurboTax does not print and mail it for you. In normal times, it takes the IRS about 16 weeks to process an amended return.
