Real Estate holding company (LLC) Taxes

I own a couple of rental property homes and each is under an LLC. Additionally, I have a Holding Company (LLC - sole proprietor)  that owns the rental property LLCs. For taxes, how do I complete since all of the properties are under one LLC?  I have an individual 401k registered to the holding company that I plan to contribute almost all of the income to. Would I still do a 1040 schedule E that has all the properties?
