Deductions & credits

What cleared this up for me was: 


The remaining amount of CTC  (emphasis added) that you can receive will show up on line 28 of your 2021 Form 1040.

I had originally thought that the value on the line was the total eligible amount including the funds already received.

    2 kids @ $3,600

=====================

$7,200 (what I saw on line 28)

 

You answer cleared up that the math was actually:

    2 kids @ $1,800 (remaining credit)

+ 1 kid @ $3,600 (full credit)

=====================

$7,200 (what I saw on line 28)

Thank you!
