expenses on rental/ personal use property

our rental was only rented for about 3 months last year and the only income was the security deposit.  we had considerable repairs when the renter moved out as well as made some upgrades.  in June , a relative began 

using the property.  can I deduct those repairs and upgrades to offset the security deposit?  if so, where do I enter this as Turbo Tax is prorating the insurance and taxes based on personal use/rental days.
