Chili Beans are typically made with either kidney beans or pinto beans. They are just beans that are in a chili sauce so make sure you don’t rinse the beans  - you want to pour all of it in so you get all the flavor. See my ingredient photo below so you have an idea of what you're looking for. You may have a different brand depending on where you live. You'll find them near all the other canned beans in your grocery store. If you can't find chili beans, you can use a combination of both or just one or the other kind of beans, whatever you prefer.
