My building (which needs major repairs) is used to store regularly needed maintenance supplies& tools for my apartment rentals. . How/where do I enter this in Turbotax?

The building was a rental owned by the LLC, but was trashed by tenant, pipes froze, etc.  For several years it has been used by my LLC business to store cleaning supplies, tools, files, & building materials for the adjacent apartment building and commercial rental.  The LLC doesn't pay rent to itself.

I can't figure out where to enter this, to deduct utilities etc.
