Does not appear that TurboTax allows you to make manual adjustments between the federal and New Hampshire activity, unless it is prompted by a form. It makes the decision for you in the NH Interest and Dividends section. What I would suggest would be adding a state to the tax return. That may give you the opportunity to adjust NH taxable income by stating these sources of federal income are not subject to NH tax. You would report it to the other state and never file the other state.
