The code 2B issue is likely that when asked if the distribution was from a Roth IRA you mistakenly answered Yes. This is a trick question by TurboTax since code B indicates that the distribution is not from a Roth IRA but is instead a distribution from a designated Roth account in a qualified retirement plan like a 401(k). Go back and edit the code 2B Form 1099-R and be sure to answer No when asked if the distribution is from a Roth IRA.
I've complained about this issue for years and Intuit refuses to eliminate the unnecessary question, saying that the it's not a TurboTax problem that the user answered the question incorrectly. It trips up many people every year.
