Child Tax Credit, Form 8812

I have a 19 year old son who is a full-time student, and I provide more than half of his support; he lives at home.  He earned $10,000 at a job during 2024.  It would seem he qualifies as a qualifying child and not a qualifying relative, correct?  The confusion for me lies on Schedule 8812.  Since my son is over 17 years of age he must be included on line 6 on that schedule, correct.  So he would be considered a qualifying relative and not a dependent child, and I would complete the appropriate line.  So then, which box must I check on my Form 1040. child tax credit box or credit for other dependents box?
