Then it's a property improvement. More specifically a land improvement since no structure exists in it's place after removal. When entering it in the Assets/Depreciation section classify it as land improvements. So on the first screen select "Rental Real Estate Property" and on the 2nd screen select "Land Improvements" and go from there. Note that there will be depreciation on this. If it qualifies for the special depreciation allowance the program will know. If offered that, I recommend you take it.
