I have another question related to this question. I went back to 2014 ( my son's first year of college) and discovered we did take a $300 credit on form 8863 line 19. I think that was the LLC. We were looking to ammend tax returns to claim AOTC for him for 2015, 2016 and 2017 and claimed AOTC already for him for 2018. Are we allowed to take the AOTC for 4 years since he apparently used the LLC in 2014?
