Only investment expenses that are entered on Forms 1099-INT, 1099-DIV, or 1099-OID are transferred to the screen titled Itemized Deductions - Other Expenses and shown as Investment fees & expenses from a regulated investment company. You are not able to add to the amount on that screen, but can enter other investment expenses as explained below.
To enter or review investment expenses (if you do not receive a Form 1099-INT or Form 1099-DIV on which the investment expenses appear in box 5, OR a Form 1099-OID on which the investment expenses appear in box 7):
Investment expenses (other than interest expenses claimed on IRS Form 4952) are deducted as miscellaneous itemized deductions on Line 23 of Schedule A. To be deductible, these expenses must be ordinary and necessary expenses paid or incurred:
The expenses must be directly related to the income or income-producing property and the income must be taxable to you.
