Business & farm

Thanks @nexchap .  Are you saying, on my 1099-B, if the stock purchase was 10,000 for example, and my sales schedule says my cost basis is 5,000, I should be editing that in the 1099-B section?  Do I check the box that says "The cost basis on my statement is incorrect" and then write 5,000?  Or should I just edit it on the main sale page where the number is imported/entered in box 1e?
