For a Trust (using Turbo Tax Business) Real Estate Depreciation

I am using Turbo Tax Business for a Trust.  For a Rental property, I am figuring about $15,000 of depreciation for the current year. But since my expenses are low,  I can't use all the depreciation.  The depreciation seems to be distributed on the K1 and not kept for the Trust.  If I had more expenses (Like loan interest payments) would the depreciation be used to offset the added expenses instead of being distributed on the Trust K1?
