Contact the IRS for clarification, but it appears as if you have a single-member LLC (with the trust as the sole member) and a grantor trust.
As a result, your single-member LLC is considered to be a disregarded entity for federal income tax purposes and you most likely should report the income/expenses from the rental on your individual income tax return on Schedule E (of your 1040).
You might want to seek guidance from local legal counsel and/or a tax professional.
