OK, that was enough information for me to be able to reproduce your results exactly, except that I think that you mistakenly typed $37,903 instead of $27,903 for line 32(d) of your results when box 11 of the code B Form 1099-R is blank. I get the same result only when the code H Form 1099-R is the first one entered and the year entered in box 11 of the code B Form 1099-R is some year before 2015, say 2010, indicating completion of the 5-year holding period.
The only thing that TurboTax should possibly be doing with the box 11 entry on a code B (or code H) Form 1099-R is use it to determine how much of the distribution becomes Roth IRA contribution basis if the distribution is rolled over to a Roth IRA. In the case where the box 7 codes and box 11 year indicate that the code B distribution is a qualified distribution, the box 1 amount becomes Roth IRA contribution basis. If the box 7 codes and box 11 year indicate that the code B distribution is not a qualified distribution, only the box 5 amount becomes Roth IRA contribution basis. However, TurboTax is making a mess of this function as well.
I suggest leaving box 11 of the code B From 1099-R blank.
I'll add this information to the details that I've passed to the moderators here.
