How do I quit my salary career job

I plan to quit my salary job in California after my leave is done.

Do I need to go back and work my 2 weeks( for the notice I’ll be giving)

Is it wrong that I plan to quit while on maternity leave?

It is also a respected place with great people I have built professional relationships with

I am not receiving benefits from my work, I am on disability/bonding from the government.
