In 2017 we converted our residence to a rental. We bought it in 2006 and the value has never recovered from the 2007/8 crash. How do I enter the cost basis?

The questions asked by the software allow me to specify that we converted a residence to a rental. but nowhere do I encounter a place to enter the Fair Market Value to establish the basis. It only lets me fill in the date of the purchase and the original cost. This would overstate the depreciation basis by quite a bit.
