After you file

@ChikNOodle Wait until your original return has been fully processed and then amend using a Form 1040X to add that other W-2.   Do not assume you will get another refund until you have completed the amended tax form.   More income = more tax, so it is possible that by adding income you may owe, depending on how much tax was withheld by the employer.
