1099-R Box 7

Retired Fed.  with special ROTH withdraw waiver for disbursement under age 59 ½.  Issued 1099-R with box 7 code 2B for such withdrawal as per Public Law 114-26, but Turbo Tax won’t allow me to transmit information as it flags this as second code “B” is not used for IRA distributions.  System won’t allow transmission until I change code.
