I filed taxes using turbotax as an international student, but I did not know I could not use it, what now?

So, I am in the United Sates on F1 Visa since 2017, I decided to use turbotax for my 2020 tax return, and have already received a tax return.I did not know that international people could not use turbotax. What can I do now to solve this situation and how do I return the money. I currently live in Florida.

 

Any help would be greatly appreciated, thank you.
