I Have Accidentally Started a Form 1040 and Need a Form 1040-X. How Can I Change This?
Form 1040-X is used to amend a tax return that has already been filed. If you accidentally started a Form 1040 return, the steps you need to take depend on whether the original return has been filed.
If the Original Return Has Not Been Filed
You do not need Form 1040-X. Simply continue working on the Form 1040 return and make any necessary corrections before filing it with the IRS.
If the Original Return Has Already Been Filed
You will need to prepare an amended return using Form 1040-X. If your original return was filed through the tax software, look for the option to file an amended return after the original return has been accepted by the IRS.
Contact Customer Support
If you are unable to access the amended return feature, need assistance navigating the software, or want to remove an incorrectly started return, contact the customer support team for the software you are using. Available support options vary by provider and may include online help, chat support, or telephone assistance.
Additional Information
Form 1040-X is used to correct a previously filed Form 1040, Form 1040-SR, or Form 1040-NR.
An amended return should generally be filed only after the original return has been processed or accepted by the IRS.
Electronic filing may be available for eligible amended returns, depending on the tax year and IRS e-file requirements.
