You say: "My parent was alive and I am under 24. That is why I don’t qualify."
No. Those two items. alone, do not disqualify you. You need the third item: your earned income was less than half your support.
The one piece of information still missing is: did more than half your support come from your earned income.
If it didn't, you don't qualify for the refundable portion of the AOTC. If TT gave you the refundable portion anyway, it's because you answered the support question wrong.
