How do I add a w2 for a dependent

[Texas Roger]

You don't enter a dependent's W-2 on your tax return. If their income is more than $6300, they must file their own return to report it. If less than $6300 but federal income tax was withheld, they can file a return to get a refund.

If they file a return, make sure they indicate they can be claimed by someone else.
