I am trying to figure out how to enter the gains from stock we sold and its asking for info on 1099 but we do not get one in the mail. You call and they give you info

What reputable broker doesn't send you a 1099-B showing the sales at the end of the Year ?

Even if you do not get one you need 4 pieces of info to enter the sale ... date of purchase, date of sale, purchase price & sales price.
