The best course of action is to
request a corrected
W-2 from your sons Employer as soon as
possible. If it's listed incorrectly it could lead to an examination of
your return by the IRS.
"If your attempts to have the Form W-2, Wage and Tax
Statement, corrected by
your employer are unsuccessful, you can request that an IRS representative
initiate a Form W-2 complaint."
Here's a link to the IRS website with
more information about W-2 replacement: https://www.irs.gov/faqs/irs-procedures/w-2-additional-incorrect-lost-non-receipt-omitted/w-2-additi...
