Reporting Qualified Distributions from Inherited Roth - TT considers them taxable

I had a small qualified distribution from an Inherited Roth.  The 1099-R box 2b says the taxable amount was not determined and the box 7 distribution code is T.  I read that with the "T", TurboTax considers them unqualified. Even after I answer all of the questions it still considers it taxable.  What am I doing wrong, or what can I enter to have then considered nontaxable (as they should be, and have been when not using TurboTax).  The original owner did meet the 5 year rule and passed in 2012.  Thanks.
