No this is not a glitch in the system. The child tax credit does not show on your 2021 return as a non-refundable credit. Because of the Advanced Child Tax Credit, the balance of the child tax credit is being treated as a Refundable Child Tax Credit. The remaining balance of child tax credit that you are entitled to is shown on Line 28 of Form 1040.
Check Line 28 of your Form 1040.
