I answered yes to parents living. We are. He is not married.
After playing with different options, if I answer “full-time” as enrollment status instead of “at least half-time”, (as indicated on Form 1098-T), it appears to calculate correctly. (refundable portion of American Opportunity Credit not included in refund) Why would enrollment status make a difference? I would think earned income providing less than half his support would be the trigger.
