After you file

@Sahara17 If you are issued a refund from the original tax return, you keep the refund. 

When completing your amended return the amount of the refund you received will be included on the Form 1040-X.  If your amended returns shows that you have taxes owed, you only pay those taxes.

The IRS Form 1040-X for tax year 2023 is scheduled to be available in TurboTax on 02/14/2024.

 

You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.


Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
