Is Interest on forgivable loan, that is used for investment, tax deductible?

My employer paid me a bonus structured as a 10 year forgivable loan.  I am a W-2 employee.  I have invested the loan/bonus into the stock market.  Is the interest on the loan tax deductible under IRS publication 550 “investment interest and expenses”?  If so, how much of that interest can I deduct and where in TurboTax would I enter it?  Thank you.
