The error message you are seeing on the wash sale entries is a result of automatic rounding. If the wash sale adjustment is $0.49 or less, then it is automatically rounded to zero. This type of rounding is allowed by the IRS.
Unfortunately, zero is not a valid value for this field for TurboTax, thus the error message.
To resolve this, you can edit each transaction and delete the amount entered in the wash sale creating a "null" as opposed to a Zero.
This will resolve the error message
