Who can file Form 1040-X?

A 1040-X form should be filed by anyone who has already filed a tax return and needs to amend it for any of the following reasons:

To correct Form 1040, 1040-SR, or 1040-NR. Most taxpayers use one of these three forms to file their annual tax returns.
To make an election after the deadline. For example, a married taxpayer can elect to file as an individual or jointly with a spouse.
To change an amount that was previously adjusted by the IRS
To make a claim for a carryback due to a loss or unused credit

What information do you need to prepare Form 1040-X?

The most helpful document you need when preparing Form 1040-X is a copy of the original tax return you’re amending. You can transfer some of the original information onto the amended tax return, such as

Social Security numbers,
your filing status, and
gross income.

You also need any documentation that relates to your changes. This can be a number of items such as proof of payment for a new deduction you are claiming or an additional W-2 for additional income you need to report. If you attached any schedules to the original return, you don't need to complete these again unless your amendments cause the numbers on it to change.
