What boxes? Depends on what you mean by "affect" the return. Are you really asking whether the dependent needs to file a return? If your dependent has tax withheld in box 2 or box 17 they would want to file to seek a refund. Or if they have over $12,400 in box 1 they have to file.
Who has to file?

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. You may want to use this version of TT for that:
