What was the source of that income? If more than half was earned income (wages or self employment) you qualify for the refundable portion of the AOTC.
@mnhemenway Said "Being under 24 does disqualify me from receiving any refund due to the AOTC".
No. Being under 24 AND meeting the conditions described in the instructions disqualifies you. Being under 24, alone, does not disqualify you. Those conditions are:
1. He was:
.....a. Under age 18 at the end of 2020, or
......b. Age 18 at the end of 2020 and his earned income was less than one-half of his support, or
......c. A full-time student over age 18 and under age 24 at the end of 2020 and his earned income was less than one-half of his support .
2. At least one of his parents was alive at the end of 2020.
3. He is not filing a joint return with his spouse for 2020.
