After you file

I am trying to amend my 2019 tax return through turbo tax (yes, I filed the original also through turbotax). I am unable to find where exactly to make the change that will make my daughter eligible for child tax credit rather than credit for other dependents. In the final filed document I can see a tick against child credit for my 2020 filing but against other dependents in my 2019 filing. My 2020 income (105K) was less that my 2019 income (150K), could this be the reason ? is the $2000 child credit dependent on income ? See below. This is how it appears in final filed document. But while amending the 2019 tax in turbotax I am not sure where exactly I need to edit to change my 2019 claim from other dependents to child tax credit.
