Wow, did not know how I missed that. Interesting is that if you place your mouse on that checkbox and right click, the menu says "about datebox".
I have two 1116 forms, one for 1099's and one for k-1's. The K-1 is Copy 2, which shows up in the forms list on the left (along with the Comp Wks). My 1099 is Copy 1, which did not show up in forms list (although the Comp Wks did). I could only access it by using quickzoom button at the top of Copy 2. AFTER Checking that box in the 1099 Smart Worksheet Part II, It appeared in the list at the left! GREAT CATCH!
