When you entered the code-2B Form 1099-R, you mistakenly answered Yes when TurboTax asked if the distribution was from a Roth IRA. This is a trick question to which the only correct answer is No. The code B indicates that the distribution is from a designated Roth account in an employer plan and not from a Roth IRA.
Edit your entry of this From 1099-R and indicate that the distribution is not from a Roth IRA.
