Exactly which box number...on which form did you put in the Savings Bond interest back in the Federal section?
IF you entered it properly in box 3 on a 1099-INT, then there is nothing else you need to do...you do not need to "Adjust" it specially for any state.
The post-INT form box you checked that started with "Maine" has nothing to do with box 3 $$. That checkbox is for $$ in box 1 where certain states do not tax the box 1 $$ that comes form state banks and Credit Unions located within their state.
