Where do I enter sale of a rental property on the COLORADO state turbotax return?

I purchased Turbotax Home and Business 2021 and used Colorado as my primary "free" state download.

 

I completed the entire state return, but cannot find any section within the "State" returns where I can enter the sale of a rental property. I entered it on the "Federal" side, and it properly recognizes what I owe the Federal Government, but it does not show me owing any taxes to Colorado. I need to know how much I owe but the program does not seem to include this feature. 

 

How do I go about getting a resolution to this issue? If there is no resolution, can I get a refund?

 

Sincerely,

frustrated.
