If you have already e-filed your return, you have to wait and file an amended return. Otherwise, you can just make the correction and submit it.
Already E-Filed and
Need To Change
If you have already E-filed your tax return and need to make
a change for any reason, then you have no choice but to wait until the IRS
processes your E-filed return. If the IRS rejects your E-filed return, then you
can just make the necessary changes and resubmit it.
If the IRS accepts your E-filed return, then you must WAIT
until the IRS has processed your return. If you have a refund due your return
is not processed until you have received your refund. If you owe taxes, your
refund is not processed until you have paid those taxes and your payment has
cleared your financial institution. Once processing is complete, you will need
to file an amended return. You can not e-file an amended return. The IRS says
you can’t. You have to print it, sign it (both the 1040 and 1040X) and
physically mail it to the IRS.
If your E-Filed return is pending, and you change anything
on your copy of your return, then you are guaranteed
to have major issues with correcting
or amending it later. So for your own sanity, do not touch anything until it’s
time, as clarified above.
An amended return must be printed, signed and mailed. The
IRS says so.
