Why am I not eligible for the AOC or the LLC when I have net tuition costs?

I have W2 income of $5400, Federal taxes paid of $315.  I started as a Freshman in college in 2021 and went to school fulltime with tuition fees of $26,581 and scholarship of $9750. I have net college expenses of $17,506 but per Turbo Tax I am not eligible for the AOC or the LLC. I am not being claimed as a dependent on my parents tax return either.  So why am I not eligible to claim either of these credits?
