State tax filing

Thanks for your message! Adding a bit more details -- 

 

I am filing my 2023 CA return. I owed 900 and but paid 1000 electronically in 2024 before April 15.

 

I need to mail my paper return now, with no check because I already paid for it.

 

My questions still hold: what address to use and how will the 100 get refunded..
