Question about Enrollment Status for 2023

For my high school kid, I am confused as to how to answer this TurboTax question: What was your enrollment status for 2023?

 

As a full-time high school student, my kid was enrolled at a city college during last year's summer as a high school student and part of a dual-enrollment program run between the school system and the community colleges that allowed them to take career-related college courses at a college for free over the summer.

 

When checking the college website to find Form 1098-T, they saw that they did not have information listed for this. Would my kid be recognized as a full-time, at least half-time, or less than half-time? These are basically the 3 choices for this question.
