I'm having the same problem and after reading many posts, folks aren't understanding.
I have 3 kids. The credit is FULLY refundable. My refund should START at $9000 and after I indicate that I've already received $4500 it should drop to $4500 as a refund. It's not doing that. The refund is starting at $4500 and dropping to $0 after I enter what I've received. There's for sure some sort of calculation error. It's frustrating!
