From what I read in another post here is that you need to think of the 1040X as a "cover sheet" of sorts and complete it and revise the 1040 to include any changes and submit them both? Also on irs.gov
To complete Form 1040-X, you will need:
Form 1040-X and these separate instructions;
A copy of the return you are amending (for example, 2021 Form 1040), including supporting forms, schedules, and any worksheets you completed;
Additional supporting forms, schedules, and any worksheets for the return you are amending that you will need to complete to show your changes;
If applicable, a new Form 1040, 1040-SR, or 1040-NR for the return you are amending (see Resident and nonresident aliens below)
From this, it would seem that I need the 1040X showing the changes, new 1040 with the changes made and the original 1040 that I am amending.
