Webnovels on AO3

This is probably something obvious, but I am a little dense, I've recently gotten into a bunch of webnovels, and was looking to see if there was any fanfic on AO3, but couldn't figure out what section to look for the different novels? Books and Literature? Other media? Categorized? There are so many good webnovels that are now getting published by Amazon, so I would think Books and Lit, but I'm not sure. My guess is the two I'm looking for don't have any fanfics, but I'd like to have a go-to category to look through in the future.
