At the very bottom of the Gains and Losses report there are two extra lines which detail the wash sales deferred to the next tax year:
TOTAL WASH SALES DEFERRED TO NEXT TAX YEAR - This is the grand total of all wash sale losses that were disallowed for the current tax year and that were deferred to the next tax year. When you run the File, End Tax Year procedure, these wash sale deferrals will show up in your next year data file with a 'W' in the open/close column for easy identification.
TOTAL WASH SALES PERMANENTLY LOST TO IRA - This is the grand total of all wash sale losses that were permanently lost to trades in an IRA account. See Wash Sales in an IRA for more details.
