@JLK20 you cannot use 1040-X --- you will file a new return using form 1040-NR or 1040-NR-EZ and attach a copy of the 1040 return filed plus a letter explaining that this was an error in filing. This is because a return must be filed using the correct form, otherwise it counts as " not filed". So IRS has to purge the form 1040 from your account. Good Luck
