Deductions & credits

I  have same issue. Would like answer on this too since last we heard TT software was to be updated March 19th

Plus how do we handle State Taxes like CT  will use the new AGI after  $10200 exemption taken by IRS but if we have already filed and the IRS will handle changes to AGI (based on 1099G  I guess) how will the state know of the update if no amendments need to be filed
