How do I access Form DR 1778 for my Colorado return

Form DR1778 should be generated as part of your CO return in TurboTax and you can print it out.

If you are electronically filing your Colorado return you can either:

  1. Go to the Colorado Revenue Online website at and select "Submit an e-Filer Attachment"; OR  
  2. Use Form DR 1778, e-filer Attachment Form, to mail in certain tax documents. After your electronically filed Colorado Tax Return is accepted, mail DR 1778, Colorado e-filer Attachment Form along with applicable documentation to:

          Colorado Department of Revenue
          1375 Sherman Street
          Denver, CO 80261-0006

          [NOTE:  This option can extend return processing time up to 6 weeks.]
