I had a traditional W-2 with taxes withheld and a Schedule C 1099 with no taxes withheld. I paid those taxes when I filed my return.
This balance specifically comes from the revised amount from EDD. I claimed 12,600 in UI income with no taxes withheld (my 1099G) and would have paid taxes owed at the time of filing.
Now I seem to owe a balance of $708 based on what they could verify from EDD which doesnt make any sense. Unless somehow EDD gave them the wrong number and it was somehow higher. Also like you said California doesnt tax UI and this letter is from the State of California Tax Board. So why would they be saying there is a balance based on my UI claim?
