client claimed son on taxes but it was the fathers turn to claim.  client received Child tax credit and earned income credit.  father filed form 8332, but child lives with mother and attends school from mothers address. How do I change the dependents status if the child lives with mother all year.  what are the credits if any that the mother is entitled to.  She also claims daycare credit.  

I have changed dependent status to H but I am not sure that is correct..  Mother earned approximately 27000.00.    Is there anything that can be done to help mother retain some of the refund?
