Even though there is no dollar change some taxpayers do prefer to file an amended return to correct the record and have on file the complete corrected tax return.
Other taxpayers prefer not to take the time and effort to file such changes and opt to simply keep the correct and complete information in their records if there is any future question on the return.
Since there is no dollar change and the form mentioned is not one which would be required each year providing an amended return will only allow the return to be changed to not include the form.
Any penalty on examination or later revision of a filed tax return is based on the deficiency, or difference between the amount paid in and the later corrected tax, so there is no penalty for not amending a return only to change the forms included.
Having included a form that provides more than the required information would not cause any change if later discovered to be in error only for the extra form.
You will have to decide if you prefer to file an amended return to try to remove the form with extra information (but that form would still exist in the originally field return).
Send the 1040X if you prefer but know there is no later consequence if you do not.
Please ask if you need more discussion or clarification.
