How to file expenses not tied to rental property

My wife and I started an LLC in 2023 for rental properties. We purchased two duplexes in 2023. My question is how do I file expenses incurred that are not directly tied to a specific rental property? Example expenses are LLC setup fees, mileage to view properties we did not purchase, and general office supplies. Do I file Schedule C for these even though all income is from rents and is included on Schedule E?
