How do I enter info on rental property on asset page when the rental was converted from the primary residence the 2nd time?

More info: I converted my primary residence into rental property in 2016. Then I moved back in 2020 (i.e., converted it back to primary residence). Now, I just converted it back to rental in 2024. What do I enter as the cost, cost of land etc on the asset page? should I enter the cost when I first bought the house?
