I ran into this problem also. I printed the Colorado return from Turbotax even though it has an "error." I went to
Colorado Revenue Online https://www.colorado.gov/revenueonline/_/ and entered all the data from the paper return. I had two DR0075EZ Forms so deleting the Form 1366 was not a choice. Colorado forms with DR0075EZ must be e-filed! I was able to attach the forms, and file successfully. The bug in Turbotax is in Line 88 Form 1366 but it is not a bug on the Colorado site. Best of all I did not have to pay the $19.95 electronic filing fee that Turbotax charges.
