Receiving an error message on 1099-R code, how do I correct?

[mmcorrey]

Box 7 Distribution codes show "B" is invalid and should not be used for IRA distribution.

[dmertz]

Code B indicates a distribution from a designated Roth account in an employer plan, not from a Roth IRA.  Make sure that the IRA/SEP/SIMPLE box is not marked.  If TurboTax asks if this distribution was from a Roth IRA, you must anwser No.
