need to know if its mandatory to show up at a judicial review hearing at child court for case plan review as the father of the child. Im not getting c

It seems that you have not been properly informed by the Court on many issues regarding this matter.  You are not mandated to attend the Judicial Review hearings, as they are in place to review the child's placement and well-being including any services he or she may be receiving along with the parents' compliance on their case plan tasks.  You may have limited access at this time, but if you follow through with the therapeutic visitation and other case plan tasks, then you could be reunified with your child and no longer pay child support.  The child support is put in place because the caregivers (aunt and uncle) are required to apply for child support in order to receive funds from the State for your child's needs.   Additionally, if you choose to only visit your child and not complete the case plan, then DCF can petition the Court to terminate your parental rights and allow your child to be adopted by whoever the Court approves.  You have a limited amount of time to comply and if you choose not to attend the various hearings then you may end up with your rights terminated and your child adopted.  I recommend attending all hearings and consulting with an attorney.
