NH DP10 Interest or dividends NOT taxable

NH DP10, question 4 asks about interest and dividends that are NOT taxable. Turbotax has filled in an amount based on my federal tax data. Two issues:

  1. I think Turbotax is wrong. I think all my interest and dividends are taxable. Unfortunately, Turbotax does not permit me to edit the amount on my DP10, so I can't delete it.
  2. If I try to leave the amount (that is, trust that Turbotax is correct), then it requires that I fill in column I with a Reason Code. None of the options apply. 

I truly think this is a TurboTax bug. I don't know how to get around it short of printing a blank NH DP10 and filling it out by hand. Any ideas?
