Hello, it's THAT time of the year again

since last year we started sending one of our 2 kids to the kita a few days per week. I have three questions regarding the tax declaration (C permit):
1) Do I understand correctly that I can only deduct childcare costs if
both parents are employed/in training or unable to take care due to illness?
2) In any case, where exactly do I put this item in the tax declaration form? I know for the "paper" one is point 16.6 of the "Abzüge" form, but I cannot find explicitly it in the
online tax declaration form. Is it "Sonstige Abzüge" and then I just write down "kita"?
3) I know there is a cap of 10'100 CHF per kid (and I know that they're gonna raise it next year), but how does it split between "Staatssteuer" and "Bundessteuer"? The form explicitly asks for these two fields.
Thanks in advance for any useful reply.
