Deductions & credits

Yes I know I put in the amount I received but because they went off my 2018 taxes they didn't give me the right amount my son was born October 2019. So I should be getting $1,100 for him but cant because its saying that I received the right amount when even the IRS is saying I didnt. And no one that i have talked to on this turbotax knows how to do it i guess.
