Thank you! It works now.
One solution I found on google is that I can triangulate the Ngon and then transform it into a quad (ALT+J) but it didn’t do the trick. Do you think maybe in other cases this is a valid answer? I think what I want to know is if it’s possible to fix Ngons when you’re so far along the way that is not possible to undo a bunch of times, while also being able to create a loop cut.
