Property Type for Rental Property

I own a mobile home park and another rental home which are my sole source of income.  When I enter in my schedule E, I have selected my Mobile Home Park as a Property Type 2, Multi-Family Residence.  When I try to take the Section 179 deduction, Turbo Tax flags my entry and states I must use either property type 4, Commercial, or property type 4, Self-Rental.  I don't know which one to choose.

 

My rental home I classify as a property type 1, Single Family Residence.
