If you are a single member LLC and are electing to file using Schedule C of your individual return, rather than filing Form 1065 for the LLC you will start by opening your return and clicking on the "Income & Expenses" tab of the return. Then click "Edit/Add" next to Self-employment income and expenses. After adding the details about your business, you will be able to enter the 5 rentals under Assets of the business (LLC).
Please comment if you need additional help with this.
