What is the "provider amount paid" on my form 2441?

How much did you pay someone to take care of your child so that you could work?     The child and dependent care credit is a credit for parents who paid someone to babysit or provide daycare while they worked.

What do I put in the provider amount paid box if I paid out of pocket around 1,200 and childcare assistance paid the rest of it? Would I just put my out of pocket money I paid to them or joined together with childcare assistance?

You only enter the amount paid by YOU---not the amount of assistance you received.   If your own out of pocket amount was $1200 that is what you use.
