Deductions & credits

I am in the same predicament. I believe I should be receiving an additional 3600 but it just subtracts what I get. One tax expert agreed with me when reviewing and stated to out I received zero in the advance which I wouldn’t do. When clicking for the explanation it reads as if I only should receive 3600 and that is a part of my tax liability and balanced out to zero. It does not read as if I qualify for a total of 7200. Is there a way to see form 1040 before I file?
