How Do I Split the Single 1099-K Between Business & Personal?

I sell on ebay under a single account with my own SS. This last year I sold off a bunch of items I inherited in addition to my regular "business" sales.

My single 1099-K covers everything. I file my taxes under my SS using T-Tax Home & Business. I have it all tracked but if I put the personal stuff into the business side it completely screws up my inventory and sales numbers.

I have searched high and low and cannot find any answers about how to input the numbers into the 2 very separate sections of the tax return.
