So I'm not sure I understand the linking on the K-1 worksheet that you are speaking of. I did, however, fill in the 199A Section C worksheet in general and it is flowing to the K-1's in their allocated amounts. On the left-hand side (showing below) you can see the Stmt C for each shareholder shows up.  I did originally turn it on in the global print options so it does print with my tax return (stmt A and smt C print at the front ---this year at least in shareholder order for a change).

But for some reason when I print the K-1s (see 2nd image), only the Stmt A prints and not the Stmt C. So as long as I remember, I go back and print another copy of each shareholder's Stmt C to go with their K-1s   That make sense?
