How to enter sale of rental property I Built on vacant lot

How to enter sale of rental property I Built on vacant lot that took 4 years to build.

do you enter the amount of the land acquired when bought or the total cost of land and all construction costs when completed, or when and if asset first rented? What are all the details of entering this info. into TurboTax Premier? Instructions are very hard to follow, would upgrade to Home and Business be of any help?
