I think the person who posted this question is not the childs??? parent or even the alleged child! Just someone trying to cause problems . Thus is why the dumbest answer in the world is best! I think I need a break!

This is unbelievable. What country  are you located?? USA? This is unlikely, however, computers do make mistakes -- 'garbage in, garbage out' .  As others have warned, you are breaking the law regardless of your location, if they find you first, then you are guilty of breaking the law, and will not only forced to pay back but also interest and even jail time.   If you contact them first, then you may get lucky and only have to pay back what they sent you. Depends on  how long you've been ripping them off.   I would not want to be you right now.

You'll be breaking the law and will be in serious trouble. How can this be? Who's fault is this? I won't vote for them................

Collecting child support for a child that is in another's custody is fraud.  There are serious consequences for fraud.    Purporting to have a child in order to collect child support is also fraud, for which, again, there are serious consequences. 
Not only would that person face CRIMINAL charges, but likely CIVIL action taken against him/her as well.
Nope, not a good idea to pull a stunt like that.  

You are breaking the law with very severe consequences

Contact the appropriate governmental agency where you are and ask. Tell them everything. Add a charge of terrible grammar/spelling as well; "your" is possessive, "you're" is for you are.
