I found my answer.
And here I am explaining with examples for others like me who DO NOT understand the technical lingo used by tax professionals.
There are two things:
1. Child Tax Credit = This is the minimum of two numbers $2000 and "The federal taxes you owe"
2. Additional Tax Credit = The minimum of two numbers $1700 and ($2000 minus the Child tax credit you receive)
Example A:
If my federal tax = $2500.
And I have one dependent child who meets the criteria,
1. Child tax credit that I receive = $2000
2. Additional Child Tax Credit = 0
Example B:
If my federal tax = $100.
And I have one dependent child who meets the criteria,
1. Child tax credit = $100
2. Additional Child Tax credit = 1700
Hope this helps.
