I wrote a paper for my English class regarding my food history as per the assignment. However, since I did not remember anything from my childhood I had my aunt and cousin give me my history. When I got my grade back today, the professor sent a sample screenshot of what was flagged as AI, and it was something that I had directly quoted and pulled from my aunt. I have the files of both the email and the voice memo of what my aunt and cousin sent me. I also have a screenshot of the phone calls I had with the two of them.

I have sent him both the sources and phone call screenshot but how else do I fight this? I only used AI as a grammar correction tool since I allegedly, otherwise have poor grammar.
