If your return has been paper-filed , you cannot change the information. Instead, you have to amend a return. See instructions below.
IRS does not allow e-file for amendment, you will
need to submit the amendment forms with related supporting documents by mail.
(Follow instructions through the step-by-step interview questions in the
program)
If your original return generates a refund, you should wait
until your original refund arrives before you file your amendment. You can cash
your check, but you still should wait until your current tax return is
resolved. Note that if you see " Do Not
File" watermark on your Form 1040-X, this means your original
return is still pending.
