Where to input cash balance plan(defined benefit plan)?

The balance of your DBP is not reported on your tax return.   If you have pension expense you need to report, that is reported on your business tax return as an expense.  

Accounting and Reporting by Defined Benefit Pension Plans

I received a k-1 expense for a cash balance plan but there is no where to enter it to get the deduction. Where is it entered

To clarify, what line was this reported in the k1 and was the K1 from a 1065, 1041, 0r 1120S?
