Question

It says I need to mail in my "forms" for my Colorado taxes. I don't remember doing that last year. What exactly do I have to mail in and where?

You will have to mail your Colorado state return forms to:

If you are submitting the form with a check or payment:
Colorado Department of Revenue
Denver, CO 80261-0006
 
If you are submitting the form without a check or payment:
Colorado Department of Revenue
Denver, CO 80261-0005


When filing a paper return, all W-2s and/or 1099s that show Colorado income tax withholding must be attached to the front of the form where indicated. The Colorado Department of Revenue does not require taxpayers to attach a copy of the federal return to the Colorado return.

I received the same email and I do not know what to mail in. I opted to e-file all my returns. What do I need to mail in if I e-filed the taxes?

If you e-Filed the returns and received notice they were accepted you should not need to mail any additional forms in. 

 

Does the email indicate that your return was rejected?  Or that some other items are required?

I have the same issue I got email saying need to submit extra form but I file through TurboTax.What should I do now?

There are a handful of situations where you might have to mail a form after e-filing. When you print a copy of your state return, it will tell you which form needs to be mailed and the address to mail it to.

Can you confirm that if I received an email from TurboTax saying that Colorado has accepted my return that I'm all done, I do not have to mail any other forms?  Thanks!

I can't be 100% certain that you don't have to mail any other forms. Have you followed DoninGA's advice to check the Print Center for All Worksheets to see if there are any documents to be mailed? 

There are some situations where CO wants documentation for certain credits/subtractions claimed on the return, and they may have to be mailed or uploaded to the Colorado Department of Revenue. 

 

In addition to checking the Print Center in TurboTax, if you are expecting a refund, you can check on the status of your CO refund here. That  should let you know if your return has been processed or is waiting for additional documentation.
