I filed before the 10,200 exemption passed and I know the IRS will refund without an amendment but what about that State? I now qualify for CA EITC. Do I have to amend?

The IRS today backed away from the indication that they would take care of the deduction and said that further information would be coming.  California will not deduct the $10,200 from AGI so your state tax liability will be unchanged.
