No. You don't enter their W2 or 1099 income on your return. It would only go on their return if they are required to file one. If they only got a W2 for under 12,400 they don't have to file except to get back any withholding taken out. If it is more or they got a 1099Misc or 1099NEC for any amount they do have to file a return.
Be sure on their return they check the box that says they can be claimed on someone else's return. That is VERY important!
