Hi, Thanks for your reply.
So I received a 1099 from one broker with 210 shares of LT uncovered sales. I have downloaded a transaction summary from the previous broker with 13 years of cost basis activity and I have entered 70 individual cost basis purchases to best account for the the cost basis. My questions is that my 70 entries are not related to the 1099 B I received but it is the back documentation to account for the cost basis of the 210 shares so I do I enter cost basis details that are not sent to the IRS on a 1099B? Thanks
