Per IRS Instructions for Form 1040-X, page 5:

You are only changing information. If you aren’t changing any dollar amounts you originally reported, but are changing information and the rules in Resident and nonresident aliens, earlier, don’t apply, do the following in respect of your Form 1040-X.

• Enter the calendar year or fiscal year you are amending.
• Complete name, current address, and SSN (or ITIN, if applicable).
• Complete Part I, Dependents, on page 2, if you are changing your dependent.
• Check a box in Part II, Presidential Election Campaign Fund, if applicable.
• Complete Part III, Explanation of Changes.
• Instead of using Form 1040-X, if applicable, update your information for advance child tax credit payments through the Child Tax Credit Update Portal. For 2021, go to IRS.gov/ ChildTaxCredit2021 for more information. If applicable for tax years other than 2021, go to IRS.gov and search for the advance child tax credit payments for more information.

You can complete Form 1040-X in the TaxAct program. If you need help, go to our Form 1040-X - How to Create an Amended Return FAQ (the TaxAct program requires you to complete the entire return, not just the sections mentioned above). If you want to print a blank Form 1040-X and only complete the sections mentioned instead, you can print the form on the IRS website and manually complete it.
