Since the State of Colorado opened late for accepting returns, they have been quite backlogged in accepting them. Please be patient and allow the Agency to process the large number of returns that came thought to them all at the same time.
They are processing them in the order they were received.
Colorado Dept of Revenue
We have confirmed that TurboTax Colorado tax returns were released, and are in the Agency's pipeline awaiting processing from the state. You will receive an acknowledgment once the agency processes your return.
