If I moved to CO in September, earning income that is MA sourced, does it make sense that my CO taxes as a part-time resident are ZERO?

I am working remotely in Colorado (since Sept) earning income that is Massachusetts sourced.  I filled out Federal and State.  For Massachusetts, it's a part-time and nonresident form with all of my income distributed between the two. For Colorado, it's a part-time resident form.  TurboTax is saying my taxes are zero in Colorado.  Is that right?
