Partnership 1065, K-1; how to deduct non-reimbursed expense?

Two man partnership, 13,000 income, 4,000 rent, 6,000 other deductions . I completed the 1065 and brought over $1,500 per partner to the K-1, line 1 Ordinary business income to be brought into schedule E.

Both partners have mileage and paid their own cell phone bills - business related. Where would this expense be noted and deducted off their 1040? What forms and lines would it be entered on?

Thanks in advance.
