What on form 1040x do I need to correct if my child who filed a tax return forgot to check the box “someone can claim me as a dependent?”

He made minimal money but wondering what adjustments I need to help him make on Form 1040x, if any. I know we need to send in his tax forms from 2024 but no where on Form 1040x is there a box to check to say that someone can claim him as a dependent.

In MY INFO he needs to change the way he answered the interview question that asked if someone else can claim him as a dependent. If his incorrect answer prevented you from e-filing your own return, you will need to print, sign and date your own return in ink and mail it in since e-filing is now permanently closed for 2024 returns.

The only way to do it is in the "Explanation Statement" reason for filing:

"Changing dependent status to: dependent"

This changes his standard deduction, so tax may change.
