I've been searching for hours for this answer. Neither the tax department nor Intuit TurboTax forums want to answer the question when there's more than one child. They all think everyone has only one child.

I'm assuming the official final answer is that each ex-spouse can claim a different child for the huge "Eligible Child Deduction" credit.

Now I have a 2nd Q. This is only good before a child turns 18. If they turn 18 let's say in Tax Year 2024, can that child still be a dependent for that tax year, because they were 17 before filing last year's return?

Or is that whole year not-applicable because they turned 18 late in that tax year.
