I decided to test it. I have desktop (not online) Deluxe. TT gave me the AOTC, even when I entered a 2nd 1098-T marked grad student. Most interestingly, it counted the grad school expenses toward the AOTC. I think this was because I indicated that 4 years of schooling had not been completed prior to 2020.
It sounds like you may have entered something wrong.
