baldietax,
Thanks for trying to help me.
Please read my response to fanfare. I addressed almost everything you also posted.
(1) I don't see any choice to attach anything to a response. Please inform me how.
(2) I'd have to attach both my 1099-B & the Excel spreadsheet. That's rather unsafe, as they contain personal information.
(3) The magnitude in terms of all you listed are large - number of sales, proceeds/cost/gain and difference vs. the brokerage 1099B, especially with the duplications. I've experimented with deleting the duplicates, but it's hard to explain how this is not only difficult & time-consuming to do, but it doesn't contain the right monetary figures - so, GARBAGE IN - GARBAGE OUT.
