I would use the Forms view to see your actual state numbers. You might even need to save a PDF of your state return as it currently stands and look at the numbers there. If your state is like mine (Oregon), it takes your federal taxable income (AGI) and then subtracts certain income items. Look at what your state has listed for subtractions and what codes it gives for them on the accompanying state schedules. Is it subtracting the full amount of your I-Bond interest income?
