Not sure what kind of supports you are seeking for your child, but you could also look into Johns Hopkins U's CTY program. They accept the scores you already have for access to programming of various kinds.
According to the College Board's website, it looks like they are hoping to administer the PSAT 8/9 this coming school year, so you could also contact your local school district about that. They were cancelled this past school year because of COVID, not permanently. (Duke doesn't administer them directly, so what TIP does is irrelevant. These scores are also accepted by a couple of other talent searches for gifted students, including CTY.)
