beyond the question @SusanY1 asked, what is in Box 1 and Box 5 of the 1098-T? any numbers in any other boxes? if so, what are they?
to simply your question, and awaiting @SusanY1 response, the 1099-Q are reported on the tax return of the person whose social security number is on the form, not who owns the 529 plan. So you should find that you child's ss# should be on the forms via the grandparents 529 plans since those payments went directly to the college. If you child is required to file, these 1099-Q's should be filed on the students tax return!
