Thanks for responding!
The way Robinhood does this is, they ask us to provide that information before the order settles, not necessarily before the sale. I would make the sale, and promptly email Robinhood support with the sale lot pick information. Unfortunately, that is the way Robinhood works for cost basis.
I have all the email that can prove to the IRS of my cost basis method. Does that suffice as evidence to make any changes against the 1099B that is reported to IRS by Robinhood?
Thanks
