When
you do submit early and find that you need to make a change, you will have to
wait until the IRS either accepts or rejects the return.
- If the return is rejected by
the IRS, then you can make the necessary changes and resubmit it.
- If the return is accepted,
then the only way to change it is to prepare an amended return and file it
by mail.
Please see the following TurboTax FAQs for more
information about amending a return.
