If the 2023 federal tax return was e-filed then you can e-file the 2023 Form 1040-X amended tax return.
The Form 1040-X for amending a 2023 tax return will be available in TurboTax on 02/14/2024.
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 16 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.
