Sissa51,

What you have is investement interest expense.

Investment Interest expense deduction is figured on form 4952, Investment Interest Expense Deduction.

The form and it's instructions may be all you need.
See IRS Pub 550, Investment Income and Expenses, starting about page 31 you will find a title, "Interest Expenses" for more information.
