Margin interest is the interest that is due on loans made between you and your broker concerning your portfolio's assets.

 

 

Please follow the steps as @Cynthiad66 stated. Additionally, keep in mind that margin interest will still be deductible for tax year 2021 as an itemized deduction on Schedule A, so if you take standard deduction, it will not be deductible.
