Investors & landlords

 Thank you for clarifying.  I'm in the process of amending my 2019 return and want to add the cost of improvements (around $40K) to the Cost Basis of the house.  When I get to the screen that asks how I would categorize this asset, would I choose "residential rental real estate" and then describe it on the next screen as "property improvements"?  What would I put for the date purchased if I'm consolidating multiple purchases acquired over 5 years?
