Is my daughter’s income zero?

[tanabird]

It says “T1, line 23600” I don’t know what to put she only gets her child tax, do I put that amount ?

T1, line 23600 can be found on your child's tax return. You can look at the Detailed Tax summary or the PDF archive of her return to see that line number.

If your child is not submitting a tax return, then yes, you can just enter her income instead.
