Why can't I go back and change the response to the question regarding health insurance plan. I dont have one and marked yes and cant' go back and change?

I don't think this is a question on your Federal tax return.  I suspect it is on the state return.  

Some states require you to have health insurance. 

If you live in one of these states, you need health insurance coverage:

• California.
• Massachusetts.
• New Jersey.
• Rhode Island.
• Vermont.
• Washington D.C.

If I've misunderstood your question, and this does not completely answer it, please contact us again and provide some additional details.

I have a similar question as the original poster.  Where do I locate the original question about whether I had health insurance -- either on the federal or on the New Jersey state taxes interview.

There seem to be several similar questions on this forum recently but none of the responses actually answer the explicit question:

where, exactly, can someone change their original answer to the question about whether they had insurance coverage for the year -- for a state that requires such information?

Thank you to the person who answered above (John B5677).  It actually seems that working with that question DID help trigger the NJ state insurance question again.  I appreciate your response!
