After you file

The "injured spouse" form does not pertain to your situation if you are waiting for child support that is owed to you.  That form is for married couples when one of them has an outstanding debt for student loans, tax debt, child support, etc. but the other spouse had earnings and wants to shield the portion of the refund that can be allocated to them.  And you are correct--you have to wait for the agency that administers the child support order to send you the money owed to you.
