How do I know if I have any community property adjustments or community income to report if I'm currently in complicated divorce which started last year but not finished?

You will need to file married-separate if your spouse will not agree to file married-joint. Your spouse would need to do the same community property allocation, unless the individual has dependents and qualifies to file as head of household. So, they will likely need your income to complete their tax return like you will. The best thing to do would be to contact them and offer your income information in return for theirs.
