DCFSA and child tax credit for amount above 5k in turbotax

I contributed 5000 towards employer provided DCFSA. I imported all W2s (me and my wife's). 

I spent more than 5k on my child's day care. When I go to Child and Dependent care credit and enter 5k or more it increases my Federal and State refund substantially but I thought I can only use one of DCFSA and child tax credit. 

Am I doing something wrong ?
