Edit the 1099-R in TurboTax and in the follow-up questions make sure to indicate on the Money From a Roth IRA page that the distribution is NOT from a Roth IRA. Code B indicates that this distribution is from a Roth account in a qualified retirement plan, not from a Roth IRA. This question in TurboTax serves only to trip you up. It's been a problem for the unwary for years yet Intuit refuses to eliminate this unnecessary and confusing question presented under these circumstances.
