How do I enter the cost of solar panels for a rental property to receive my 30% tax credit, on the on-line version of Turbo Tax Self Employed version?

The Residential Energy Efficient Property Credit is not available for rental properties.  Only personal residences where you live.  See the Form 5695 Residential Energy Credits instructions - https://www.irs.gov/pub/irs-pdf/i5695.pdf

I realize that, however the 30% business tax credit is available. My version of Turbo tax Self Employed does not show a link to the Business section. Why not?
