Entering info for cost of furnace in rental property: Expense/Depreciation

Confused by prompt screens: I have a single family rental and replaced the furnace at a cost of $3000. Here's where I'm at.

- Do you have any items for this rental prop that aren't covered by your elections

               • Yes

Property Assets

               • Add asset

-Describe this asset

               • Rental Real Estate Property

-Tell us a little more about your rental asset 

      -How would you categorize this asset?

* This is where I'm a little confused and assume I enter "Residential Rental Real Estate" rather than appliances, carpet furniture or Landscaping. Where do I go from here? Am I on the right track.

** I also have a sidewalk ($1600) to write off. I assume I follow these same steps to this point and then choose landscaping?

Thanks for helping this tired old mind.
