The same thing happened to me this year. I've never been asked to submit receipts to the state before, either. I'm guessing it's a glitch but I'm not sure if I need to do it? The CO state tax book says, "For claims greater than $5,000, submit the receipts you received at the time of donation. For in-kind donations, submit an itemized list of the donated items and their fair market value. Submit using Revenue Online or include with your paper return. Do not send receipts of items that were purchased for donation." Mine is less than $5K total. Do I just submit receipts for the stuff I donated at ARC/Goodwill in kind? That seems unusual.
