I had $10,000.00 in management fees in 2016 and $900.00 in subscriptions in financial publications, where do I enter them?

They would be entered under

federal taxes, deductions and credits, retirements and investments, then other investment expenses.

Remember that these expenses are subject to a 2% exclusion and there are eligibility requirements for these expenses

Eligibility requirements

 - You must itemize your deductions on Schedule A in order to claim these expenses.

 - You can deduct safe deposit box rental fees when you use the box to store documents for taxable income-producing investments, such as stocks and bonds. If you also use the box to store tax-exempt investment documents or personal belongings, such as jewelry, then prorate the portion of the box that is used for your taxable income-producing investments.

 - You can deduct fees paid to a trustee to administer your IRA if the fees are billed separately for the IRA and are considered ordinary and necessary. Fees paid from funds in the IRA account are not deductible.

 - You can deduct advisory fees and expenses used to manage your investments that produce taxable income.

Examples: Fees paid to a financial planner, tax advisor, or attorney for advice, and services to produce or collect taxable income.
