Colorado Senior Housing Credit

TT instructions for Senior Housing Credit are misleading.  The instructions mentions that if a filer has "Homestead Exemption" they should not file for Senior Housing Credit.  TT instructions should also say "Disabled Veteran Exemption" as well.  I do not have Homestead Exemption but I do have Disabled Veteran Exemption.  I have since learned that both are handled the same in Colorado.  Because the TT instructions do not mention the Disabled Veteran Exemption I indicated I was eligible for the Senior Housing Credit.  Colorado Dept of Revenue sent me a letter saying I am not eligible for the Senior Housing Credit as I have the Homestead Exemption (i.e. Disabled Veteran Exemption).  They are reducing my refund by $400 and asking me to prove I do not have the Homestead Exemption.  And according to their website are holding my return in limbo.  Turbo Tax you made the mistake.  How do I proceed???
