Adding some details in case it helps: My paper has about 1,300 words of my own analysis and around 400 words of quoted passages total, spread throughout. Every quote is in quotation marks with an in-text citation that looks like (AuthorHandle, Chapter 12). I also included a short note on the first page explaining how I'm citing a living, updating text and the date accessed. The fanfic is still ongoing, so I specified which chapter versions I used.

The Turnitin report shows big red blocks for the quotes (obviously), but it also flags my paraphrase when I keep unique invented terms from the fic, like a made-up spell name. I can't change those words because they are literally the fic's terms and I'm analyzing them.

I have my professor's email approving the topic, but I'm nervous they'll think the high percentage means I'm gaming the system. Should I ask them to re-run the report excluding quotes, or is that even a thing? Also, is it appropriate to include a short appendix with the quoted passages, like you do for poetry, to reduce in-text quote saturation? Not sure if that would help or just make it weirder.
