How do I file the cost of improvements to my rental home? It keeps taking back to add an asset.

[SabrinaD2]

To enter your rental improvements, simply follow the directions to enter your rental income and expenses. '

1. At some point you'll come across the Here's [your property's] rental property info screen. Under Expenses / Assets (Depreciation), select Add expense or asset and follow the onscreen instructions. 
2. TurboTax will figure out which depreciation method works best in your favor.

Reach back out if this does not work.
