Where are 401K deductions reported for H&W LLC?

[David]

H&W are the only LLC members of their company. They have enough profit to take the full $53K max 401K deduction for each of them.

Where is this reported?

It doesn't look like it is reported on the 1040. So do I simply take the full $106K deduction on the 1065? It shouldn't be exempt from SE tax, should it? That's why I thought it wouldn't be reported on the 1065.

I can't find exactly where and how to report this.

Thanks.

 Look at box 13 with code R.  Make sure you treat the deferral as guaranteed payments.  Report on line 28 of the 1040.
