You need to Review/Edit the existing entry. I'm working with my PC, so apologies if the online TurboTax path is different. The options should be similar...
I go to Federal Taxes > Wages & Income > I'll choose what I work on
Scroll down to the Interest and Dividends section, and it should give you an Update button next to the item you want to change. My screen shows a down symbol to the right of each entry. Click on that and you'll get the option to edit the item. Click through until you get to the 'uncommon situations' question.
Click 'None of these apply' - it should be the last option. Then continue normally and save.
You should see a difference in your NH Tax Due box immediately. I hope this helps.
