How do I access Form DR 1778 for my Colorado return

[IreneS]

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 www.colorado.gov/revenueonline 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.]

Is there a way to validate that my vehicle purchase invoice attachment has been successfully submitted on the online portal?

All I got was a confirmation number

If you are referring to Colorado Form DR1778, and you are not comfortable that your vehicle purchase invoice attachment was successfully uploaded to their website for the DR 1778 - E-Filer Attachment Form:

You may wish to contact the Colorado Department of Revenue directly. Otherwise, the confirmation number you received can serve as evidence that it was submitted.
