I have a client with that owns a commercial real estate property.  The client has a variety of commercial tenants that pay rent.

The client replaced the roof on one of the buildings in 2019.  Is there a special way to enter it in Lacerte if I want to take Section 179 for the entire amount of the roof?  On Screen 22 (Depreciation, 4562) if I enter the amount in "Current Section 179" and enter the Method as "87" for 39 year Non-Residential Property, Lacerte returns a critical diagnostic warning that my method isn't eligible for the Section 179 deduction.

Should I be entering these details in another manner or on another screen?

Thanks for any assistance you can provide.
