I don't know if this will help or not. I had a bunch of trades flagged as wash sales. It appears the issue occurs only if the wash sale amount is less than $.49, it should be rounded to 0. I believe that TurboTax did indeed round it to 0, but left an 'x' in the box. I simply 'overrode' the 'x' by deleting it and everything worked fine. I won't vouch that this is a perfect fix, but the form never goes to the IRS, it is used for TurboTax's internal bookkeeping.
