For the new child tax credit ... if I have a 6yr old and a 17yr old, my total CTC should be 6600 - 3000 I've already received, my credit on my return should be 3600?

The IRS is sending out letter 6419 to you.  It will show the amount of advance child tax credit that you received during 2021.  Enter the information from that letter carefully.   The remaining amount of CTC that you can receive will show up on line 28 of your 2021 Form 1040.

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

NOTE:   The CTC is indeed a “credit” that can be applied toward any tax liability that you would otherwise have to pay as “tax due”  to the IRS.

If your child turned 6 in 2021 you do not get $3600---you get $3000.
