Turbotax says I need to send docs to CO State separately from my return. Sale of inherited home.Where do I find out which docs? Second time I have asked this question.

You would need to send in any documents to substantiate the State of Colorado income.  In your case, since you sold an inherited house, send in the Form 1099-S you received from the sale of the inherited home.  State of Colorado Info

I am sorry you had to ask twice.
