ILR - adding daughter to application?

Two questions if I may

1. My daughter was born here and is a British Passport Holder. The only Question I've answered relevant to her is:

Do you and your partner have any children together? Yes.

My question is - do I need to add her as an additional applicant? She has a passport so I assumed no, but with the answers like this I am not getting an option to add any more detail on her, nor is it telling me to add some of the stuff people said they added:

If you have any children under 18 living in the UK:
- Each child's passport.
- Each child's birth certificate.
- A letter dated in the last 3 months confirming each child's address (i.e. from GP or school).
- No IHS Surcharge!

2. For showing salary income, I receive a bonus etc, but when I note my annual income, can I just put in my base salary (covers the amount) and then explain the increased amount some months due to bonus (matching obviously with bank statements?)

Thanks
