@Osc-ris5 ,
I think you are a victim of the clunky ordering of the questions by TurboTax. Once you have calculated your cost basis from the like-kind exchange (Form 8824), you must go back and enter that information. The "New rental property" can consists of multiple assets. The primary asset is the building itself (cost basis from form 8824). However, you may have other assets (improvements) that you added, such as a fence, a shed, a garage, etc. Your "New rental property" needs review; specifically, you need to go back and add the assets to the property.
I hope this helps. (I'm not familiar with the online version, I always download the latest version on the PC.
Blessings.
Randy
