I am having a related problem: According to the accountant that prepared the K-1, "All items from Box 13, code R on the K-1 go on line 28 of form 1040 schedule 1 as Self-Employed SEP, Simple and qualified plans." However, Turbo Tax is capping line 28 to 15,500, which traces back to the Keogh, SEP, and Simple Contribution Worksheet, which in Parts IV and V is limiting the much higher 13R amount shown in Part I of the worksheet to 15,500. Also, the 13R amount is a combination of different plans: (1) cash balance plan; (2) retirement plan; and (3) 401k. According to the accountant, "The voluntary 401k and retirement plan fall under qualified, defined contribution plans and the cash balance plan falls under the qualified defined benefit plan." I am having difficulty figuring out which category(ies) these correspond to in TT (Keogh (sub-types deferred, profit sharing, etc); SEP; Simple; 401k, etc.)
