When filing IRS Form 1040X Amended U.S. Individual Income Tax Return, it is important to attach any forms or schedules used to figure the revised tax.

As it is not possible for the program to know which forms or schedules those may be, it is up to the taxpayer to print and send them with the amendment.

In the amendment section of the Q&A, on the screen titled Amended Return - Mail Form 1040X, the first paragraph states "Mail Form 1040X and any accompanying documents to the Internal Revenue Service Center for the place where you live."

The last paragraph states "Form 1040X cannot be filed electronically. Attach only the supporting forms and schedules for the items you changed. If you do not attach these supporting forms and schedules, your Form 1040X may be returned."

To view this screen in your TaxAct® return:

  2. Click Amend Federal Return directly below the tabs. On smaller devices, this option will be listed under Filing after clicking on in the upper left-hand corner.
