Deductions & credits

I've got a gain from the sale of a primary residence in Colorado that qualifies for the $250,000 exemption on federal taxes. If my federal capital gains tax on the sale of this property is $0, does it mean that I also have the exemption on state taxes too?

 

I'm getting the impression that this is the case, but TurboTax keeps giving me the opportunity to enter a different number on my Colorado state taxes than on my federal taxes.
