" I would really like someone to take 10 min to review..."
No one in the user forum has access to your tax return, nor can anyone else here "review" it for you.
You do not provide any details of what the IRS says is incorrect or what you think might be wrong with your form 8812 for the child tax credit.
For tax year 2022, the child tax credit maximum is $2000 per child for children younger than 17 years old. That credit is applied toward your tax liability; if your tax liability is at zero, then you may receive the refundable "additional child tax credit" based on how much you earned by working.
If your child was older than 16 at the end of 2022, but can still be claimed as your dependent, then you can get the $500 credit for other dependents for the child instead of the child tax credit.

We could be more helpful if you provide some details as to what is lines 19 and 28 of your Form 1040, as well as some details as to what the IRS letter says.
