In my Federal Review it says "Form 2441: Provider amount paid-2 must be entered". How do I get back to where I can enter all of my childcare? It originally only let me enter one provider info. b/c I already reached the max. of $4,000 credit.

Enter 2441 in the Find window at the upper right, hit enter, then click the Jump To that appears.  There is no maximum of $4,000 for this credit.
