Get your taxes done using TurboTax

This is for '21 taxes and I'm looking at the worksheet that calculates line 5 on form 8812 and it doesn't say anything about the CTC.  When TT calculates it they come up with $4650 which I cannot come up with when looking at the calculations for the worksheet.  The worksheet just asked how many kids you have that I can see.  It makes no sense to me.
