Why is my Colorado return still showing as pending 5 days later?

I filed on February 10, Colorado started accepting returns on February 12.

CO is very slow. Known problem.

CO opened late for accepting returns this season. They are now processing returns in the order they were received. 

CO Department of Revenue.

Once accepted, you can check the status of your state income tax refunds,  at Tax.Colorado.gov – just click on the “Where’s My Refund” banner.
