The issue seems to be that there is no clear guidance on when additional documentation is required. There seems to be a $5000 threshold, and that is referenced when TurboTax asks about additional charitable contributions in the CO state return. From reading through the documents, I am interpreting the requirement as only needed for single donations over $5000 or non-cash contributions. With that said, I think that TurboTax printing the E-filer attachment is a bug. We had almost identical charitable contributions last year and TurboTax did not check the "Qualifying Charitable Contribution...." box (we did have Enterprise Zone Credits in the past so have done the upload process for those).
