E-Filer Attachment Form - Charitable Contributions

TurboTax told me to print  an additional form for my Colorado state taxes.  I did not itemize even though I listed donations on my federal form.  Turbo Tax recommended that I take the standard deduction.  Why am I required to send this form in with receipts to the state?  I reviewed the State forms and looked through the donations but there is nowhere to list qualifying charitable contributions and I do not see the donations anywhere on the state return.   Why am I required to send in DR 1778 E-Filer Attachment Form when I did not itemize?   

I filed the same way this year as I have in the past and was never required to submit this form with receipts.
