No, you do not "get" $4K per child. Before the tax laws changed for 2018 and beyond there used to be a personal exemption per child of $4050--which lowered the amount of income you were taxed on. (It was not a refund) But personal exemptions have been eliminated.
Your refund is not broken down by how much you "get" for each dependent.
There are several child-related credits you *may* get if you have a dependent child and if you have income earned from working.The amount earned by working has a major effect on how much you receive for the child-related credits.
You might be getting the Child Tax Credit--that is not all a refund--it lowers the tax you owe, up to $2000 per child, but if you do not owe tax then you may not get the full amount of CTC. In some cases, you could qualify for the "Additional Child Tax Credit" which is a refundable credit, and would increase your refund. If you qualify for this credit, TurboTax calculates and automatically adds it to your refund.
You might be able to claim the child and dependent care credit if you paid someone to take care of your child so you could work. This is not a refundable credit, so it will not be in your refund. It can lower the tax you owe.
You might qualify for Earned Income Credit, which is a refundable credit if you worked and earned income. The EIC is based on the amount you earned. If you do qualify for EIC, TurboTax automatically calculates the amount and adds it to your refund.
Look at your 2019 Form 1040 to see the child-related credits you received
