Deduct Interest Paid on the Purchase of an LLC

I purchased an additional 10% of our LLC (taxed as Partnership) from a partner as of 1/1/15. She and I signed a note payable and I have been making payments which included Interest. What I can’t find good information on is if I can deduct the interest against my LLC income on Schedule E Part II or if it has to go to schedule A.

 

Of the purchase 98% has been allocated to Goodwill and is being amortized as a 754 election and the other piece was a capital purchase of essentially the cash and office furniture.

 

All income from the LLC is self-employment income so there is no investment income to offset on schedule A which makes that deduction meaningless. There is a much greater benefit to it being on Schedule E, but I don’t want to do anything incorrectly. Do you know what the regulations are about this?
