When I right click to go to line 2n for input it just goes to the pass thru K-1 input for one of the nonpassive partnerships - isn't there a worksheet that shows the actual calculation for the line - this client has 2 non passive partnerships and 2 non passive S corporation K-1s and I can't determine if the figure on Line 2n of Form 6251 is calculating correctly.  Where do I find the calculation source?
