    Yes, any federal changes that impact the state return need to be reported to the state. 

    You can check the full requirements, deadlines and instructions at your state's revenue agency website.

    "Yes, any federal changes that impact the state return need to be reported to the state. "

    That begs the question that I asked. What do I do. Your answer assumes someone knows what the correct papers are. Your answer is "do the correct technical thing", that works for you. If someone does not know the correct papers, do they send the whole federal amended forms to the state? Is there a people person who can help me?

    Sorry for the confusion, yes, you need to attach all pages of your amended federal 1040X to your state amended filing.
