State tax filing

Hi, Isabela: Just to follow up on your June 1, 2019 answer to the question on K-1 passive loss carryover.  I have received one K-1 with loss.  Part III box 2 is negative.  I am in the east coast and the asset is in Colorado (I have never lived in Colorado).  I have no other gain or loss from Colorado.  I know with the loss, I do not have to file Colorado nonresident tax return.  But should I file to ensure the passive loss is covered year over year that I can use the passive loss carryover in later years?  Or Can I file only when Box 2 turns positive in a few years and then report accumulative passive loss carryover then? Thanks
