How do I request an out of state transfer of jurisdiction from Denton Texas to Durango Colorado?

Originally divorced in Denton Texas, I was awarded primary custody of our minor child with the right to move out of state. I have lived in Colorado for over two years with our son where we have appeared in court and received orders from a Colorado Judge modifying parenting time and child support. The Texas Attorney General will not enforce the child support modification unless we can provide documentation showing Colorado having jurisdiction. I recently mailed in a Motion to Transfer Jurisdiction. I was informed by Denton County that my motion was filed and would continue to sit in a file unless I "pursued further action" to get it in front of a judge. How do I get this motion in front of a judge?
