double taxed in CA and IL

Hi everyone,

 

I had income in CA that was incorrectly withheld from IL tax in 2022. I was withheld $19k to IL, which is $9k more than it should have been. When I filed my CA return, it said I owed $3k to CA. But the strange thing is, after I entered the payment I have made to IL, it says there's still a balance of $1132. This doesn't make any sense. I have paid $9k extra to IL but it doesn't offset the entire $3k balance owed to CA? Aren't I still being double-taxed despite claiming the tax payment credit?
