Deductions & credits

I have 2 daughters. One is 4 years old, born in 2017 and the other is less than one but born in 2020. I should have received additional stimulus for them as both of them were born in 2020 or before, but I didn't have a social security number for them. I have them now and should be able to get the funds that weren't available to me previously, but TT is saying that I've gotten all the stimulus that I qualify for. I don't make more than 75,000 a year. Not even close.
