File it "as if" you don't have an LLC at all. Remember, an LLC is considered a disregarded entity by the IRS. Additionally, rental income and expenses are reported on SCH E no matter what. There are not exceptions. So if rental property is the only thing you have in your LLC, you have absolutely nothing to report on SCH C. All rental income and expenses are reported on SCH E as a part of your personal 1040 tax return.
