Deductions & credits

Still no answer as to how do we handle State Taxes like CT who will use the new Federal AGI after $10200 exemption taken by IRS. But if we have already filed Fed & CT State and the IRS will handle changes to AGI  then how will the state know of the update if no amendments need to be filed. Have you seen any State announcements saying they will automatically adjust the AGI to account for the $10200 exemption.
