Your question drops off in the middle of a sentence, and it omits a critical fact -- where you are living now. If you remain in the jurisdiction that entered the order (apparently SC) then under UIFSA that State retains exclusive modification jurisdiction ("CEJ"). If no one is living in the jurisdiction that entered the order, then you must move to modify it where she is living (apparently Hawaii) and if she wanted to modify she would have to do it where you are. Full details in the article "The Basics of Family Law Jurisdiciton" posted here.
No matter which state is appropriate, however, the existing order should have called for termination of child support for emancipated children. You probably need to assemble all of the actual facts (who paid what, when) and orders, and consult with a family law specialist in the place that has jursdiction to modify the existing order.
