You will receive an email informing you that your return has been accepted or rejected by the IRS. If the return is rejected, you will be able to make the necessary changes. If your return is accepted, you will need to amend your return.
Once your return has been accepted, you will not be able to make any changes until after your refund has been processed. Amending your return means filing a new form, 1040X. This is only required in certain situations. In other situations, you can change your original return and you should not file a new form.
You should not try to amend your return until it has been fully processed and you have received your refund or your payment has cleared. Amended returns do not “catch up” to your original returns and replace them. They are processed as two separate returns.
