If you have already e-filed, you will need to wait until your return is accepted or
rejected by IRS / the state.
-If
your return is rejected, add your new information (along with anything else
that needs to be corrected)
and then re-submit your
return. See
Fix
a reject
-If
your return has been accepted- 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, this means
your original return is either still pending or forms are
not finalized yet.
