Why does TT utilize previous (carryover) foreign tax credits (first), instead of using up the non-refundable portion of the child tax credit ($400 of the $2000)?

[US family in Canada]

On my return, it appears that Turbotax automatically is using up foreign tax credits (from earlier years), instead of 'eating up' the non-refundable portion of the child tax credit ($400 for 2023). 

I am an expat filer and prefer to use up the child tax credits... and then dip into the carryover foreign tax credits (if needed). 

I cannot carry the non-refundable portion of the child tax credit forward, so it would be preferred to use this up, before utilizing my carryover foreign tax credits.

Thank you in advance for your help!
