I have 2 dependents, am married filing jointly, and have only received $4700 total stimulus. I feel like one dependent is not being counted. Am I missing something?

TurboTax is saying I got the right amount. I made under $130k last year. By my calculation I should have gotten $3400 (2 x $1200 and 2 x $500) and $2400 (4 x $600) = $5800.
