Wash Sale Loss Disallowed Adjustment Code Not working

Form 1099-B Worksheet (MORGAN STANLEY CAPITAL MGMT) -- Capital Asset Sales Wksht (1):

Adjustment code(s): Adjustment code(s) should not have an entry when a disallowed wash sale amount is entered. Remove the disallowed wash sale amount and include the adjustment here, or remove this manually entered adjustment code.

I could use some assistance fixing this error. I've tried entering the adjustment code W should I be using a different code? When I removed the adjustment code N is auto populated by TurboTax.
