@Chukis001 That doesn't sound right. Did you/she enter that she can be claimed as a dependent? Better check that. She should only be able to get back any withholding taken out which you said there wasn't. Did she get a W2 or a 1099NEC? Are you sure it's not a Tax Due of $1,500?
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.
