I have added one 1099 and cannot find a way to add a second
What type of form 1099 as there are almost two dozen? 1099-R, 1099-INT, 1099-DIV, 1099-S, 1099-B, SSA-1099, 1099-G, 1099-MISC, 1099-NEC, etc.
What kind of 1099? Enter it the same way as the first one. Like for Interest and Dividends, go to
