I got American Opportunity twice, what should I do?
In 2018 I got the American opportunity credit. I looked at my 2019 tax return and I see that it says it wasn't claimed (by mistake? I was using Turbotax) in the last 4 years (part III, line 23- checked "no"). I still got the return. From my understanding, I wasn't supposed to get this again? What should I do? I am still in college and will only graduate next semester (December 2020). **EDIT: I would like to add that I am an international student on F-1, and I do not believe I am a resident alien. Therefore, I am worried that I shouldn't have claimed these at all. What should I do? I am willing to repay these funds.
