a return that has been e-filed and  already accepted, cannot be changed.  If you missed reporting an income item, your options are  (a) after your  field return has been processed and refund issued , you file an amended return--1040-X --paperfile and reconcile your income and  taxes thereon OR you can wait till IRS discovers the issue and send you a bill  ( and  probably charge interest.  Personally I would suggest filing an amended return after you are sure that your return has been processed -- usually about 4 weeks from iniital acceptance ( to process )
