did you submit the amended return? if you did that could delay the processing of the original. if the iRS catches the omission, it may just adjust the original refund amount. do nothing until you hear from the iRS. if you have not submitted the amended return, wait until the original is fully processed. if the iRS doesn't catch the error and sends you the full original refund amount then you can file the amended return and go to the iRS website to arrange payment. don't forget about state taxes if you have them.
