Thanks to the advice (and trailblazing) of a couple folks here....Schwab has now agreed to create a 'letter' for each of my eight accounts that they will provide to me in a PDF.
I called the Litigation Settlement firm ( 1-866-274-4004) to see if that would work-- and whether to mail that or send online.
Condescending nice and as helpful as a rock.... she eventually suggested that I complete the online form (https://cytodynsecuritiessettlement.com/file-a-claim-online/ ) with total numbers bought/sold and attach the PDF's of Schwab's letter for each account to show all the transactions. (Had originally said it was the transaction numbers that they needed.) She responded with a weak 'yea' when asked if they would let folks know if/what else would be needed to complete the filling by the deadline.
Almost like they don't want to us to file.......
