I am 73, my Roth was opened in 2009, so why does turbotax include my Roth payout as taxable?

It should not.

What code is in the 1099-R box 7 for the Roth distribution?

Code T indicates that the issuer do not know if the Roth was held for 5 years.  Be sure to answer yes to that question in the interview.    The box 1 amount should be on the 1040 form line 15a and zero on 15b for the taxable amount.
