I live in Colorado. Is it true if all exemptions aren't listed you loose them and should exemption 42 407 be listed for my Social Security Disability

In order to claim an exemption, a debtor must provide a list of exempt property. Failure to timely list exemptions may result in a loss of the exemptions and would require the debtor to file a motion with the Court for permission to file the exemption list.  Social Security should be listed as exempt property. 

Note:  Exemptions may also be lost by a debtor by incorrectly characterizing the property as exempt and receiving an objection from the trustee or a creditor, or from other actions of the debtor.
