There used to be a useful toggle until last year for "Dependent with ITIN (for CTC)".  For some strange reason, Intuit doesn't find it helpful to re-purpose this toggle and removed it altogether.

There are still toggles on Screen 2 to suppress EIC and CTC but choosing to suppress CTC will have no impact on the partial credit of $500 (you would think otherwise, right?).

That leaves you one option, which is to call on our all POWERFUL "-1" and enter that on Screen 38.2 under "Child tax credit and other dependent credit (Form 1040, line 12)" as an override.  Voila, the problem is gone 😜
