Get your taxes done using TurboTax

Finally was able to figure it out.
See the first page of your colorado returns, it gives specific instructions on what needs to be done

 

Eg: there are sections labeled

1. what needs to be mailed 

2. what you need to keep

 

FYI: you do not need to mail, you can submit online as well. see screenshot
