Go to Federal Taxes -> Deductions & Credits -> I'll Choose What I Work On/Jump to Full List ->Scroll down to Retirement and Investments, and choose Other Investment Expenses or Interest Expenses. See attachment.
NOTE: You must be itemizing and can only deduct the expenses greater than 2% of your AGI. But enter them here anyway and let the software determine whether or not you can take it.
