Archive pages?

I’m not sure which of the listed templates to edit for my categories/archives. My most intelligent guess told me that it was page.php, but nothing i nudge seems to budge? I am possibly losing my mind here.

This is my site: https://www.sandradans.com
And this is the page i’m having trouble with: https://sandradans.com/love/?cat=3

Any help would be appreciated!
