One of our rental properties that we had in 2018, and reported through TurboTax 2018 does not appear on the 2019 list of rental properties.

Relaunch TurboTax and update the prior year's file again.

The property just reappeared when I brought TTax up another time. I was able to post current year information to it so it appears to be a non-issue now. Reconstructing the history of the property sounds like a difficult process...depreciation, capital improvements, adjusted cost basis over years. The fact that the property didn't appear to begin with is an Intuit issue that looked into and resolved.
