Do I need to add my children’s w2 to my takes if I claim them?

No.

MY DEPENDENT HAD A JOB

If your dependent has a W-2 for his after-school job, summer job, etc. you do not include the information on your own return. You can still claim your child as a dependent on your own return.  He/she can file his own return for a refund of some of his withheld wages (he won’t get back anything for Social Security or Medicare), but MUST indicate on it that he can be claimed as a dependent on someone else’s return.  (Supervise this closely or prepare it for him!)

If your dependent’s earnings were over $400 and were reported on a 1099Misc or 1099NEC then he must file a return and pay self-employment tax for Social Security and Medicare.

No, your children need to file their own returns with their w-2 incomes.   You can still claim them, just don't include their income on your return.  And when they complete their returns, make sure they mark the box that say 'someone else can and will claim me'.

You do not enter a dependent child's earned income from wages reported on W-2 on your tax return.  They can file their own tax return and if they do make sure they indicate on their return that they can be claimed as a dependent.
