American Opportunity Tax credit for highschooler

My son is in senior high school, will graduate 2025. In 2024 we paid $450 to transfer 2 AP courses into 6 college credits toward his bachelor degree. We also paid $500 admission deposit to the college in Dec 2024. He received 1098-T for 2024 from the college with a mark “at least half time” for $450. Question, should we claim AOTC on our tax 2024 for $450, or $950, or $0? We expect our AGI will be $180K+ by his 2nd or 3rd year of college.
