I looked at my download file preview from MS, and it included the Adjustment code N in the transactions, which is not right, as this is my account trades, not a nominee.
As others said you can put a zero in but if you still have an N in the sales file. And if you have a transaction with a wash sale, (showing NW) there is no workaround to get out out of an error situation in that case.
I think they need to adjust the ETrade by Morgan Stanley downloadable Sales data to remove the N from the adjustment Code field in the import file on these transactions.
