Do I have to enter the sale of my rental several times? For example it asks about the home in 3 sections. Rental Properties, Sale of business property, and sale of home

No, you do not report the sale three times.  The rental property should have been set up as "Rental Property" in TurboTax.  You report the sale there.  You do not report it as sale of business property (it is not), and you do not report it as the sale of your home, it's not - it's a rental property.
