I agree with the analysis of @gattaca that this problem is related to the inherited IRA being inherited from someone other than a spouse, and the presence of the new question about the year-end value of the traditional IRAs, which were not seen in previous years and are not relevant to calculating the taxable amount of the inherited IRA.
It seems that there is enough detailed information in this thread for TurboTax to identify and resolve the problem (info from @dwb54A , @gattaca and myself). So how do we get the TurboTax developers to actually acknowledge and fix the problem?
