Business & farm

I have one more issues now. On these 3 forms below, I have them on only one of us (ie Husband's Schedule C but not on Wife's). As a result, one of us has loss on Schedule C and other has profit and needs to pay Sellf Employment tax.
Forms: (1) Car & Truck Worksheet (2) Form 8829 "Expenses for Business use of your home" (3) 4562 "Depreciation and Amortization"

I was to distribute them equally between both of us. How do I do that?
