It looks like we've only used the AOC three (3) times. Once in 2018 when he was still in high school, and again in 2019 and 2020. I've used TT for the last 10 years straight, so I'm not sure why it didn't show up in the 2021 taxes, but will look into having him claim it on his 2022 return, along with adding the claims for food, lodging or the allowance as suggested.
Thanks again!
