I suggest logging in to see if your TurboTax account indicates that Colorado was sent, perhaps it had to be mailed. Go ahead and download the return, and see if you can find any instructions. There are TurboTax agents that are on the phone, who can check that for you. You can also contact the Colorado department of revenue:
