Your question is confusing ... how can a Partnership "OWN" a sole proprietorship ?
And the ONLY income for the Partnership comes from the Sole Prop ?
And how can the expenses get passed thru from the Sch C to the Partnership ? Either the expenses are paid by the Sole Prop or the partnership ... how can expenses be passed thru to the other entity ?
This is an odd set up ... but if the sole prop paid the partnership for "services/goods" then all the income the Sch C takes in goes on the Sch C and an expense for the amount they paid to the partnership is taken ... use the casual labor category for the expense and issue them a 1099-misc.
Expenses paid by each entity is deducted on their respective returns depending on who actually paid them.
Then the partnership return must be completed first (especially if you are personally a partner) and each partner will receive a K-1 to enter on their personal tax returns.
Seek local professional assistance if you are still have questions especially if this is the first partnership return you will be filing ... that form 1065 was due back on 3/15 so unless you are on extension the penalties are piling up monthly.
