Hello, is there a way to split the CCB 50/50 with my separated spouse in Turbo Tax?

CCB cannot be divided among two people. They ask this question to make sure if you are the only one who is claiming it not anyone else.

Who can apply- Canada child benefit
Who can get the Canada child benefit, who is primarily responsible for the care and upbringing of the child, and impact of shared custody on your benefits.

For more information please refer to this CRA link.

Thanks for choosing TurboTax.

And  This is the USA forum.  Here is the Canada forum
