Investors & landlords

I answered to the negative and arrived at "describe this assets".  I selected "real estate property". The next page is asking me how would you categorize this asset?  The chooses are: Nonresidential real estate, qualified improvement property, and specified qualified improvements.   The best fit is nonresidential real estate.  However, this gives me depreciation over 39 years.  I'm pretty sure it should be MACRS 27.5 years.  Been stuck here for 90 minutes.
