Found where to input in Step by Step. It is input in the Federal Section under: Personal - Deductions & Credits -Retirement & Investments - Other Investment Expenses. Choose "Enter my Expenses". Then If you then go on and enter Investment Expenses, it will populate line 24 on NY Form IT-196. Beware, however, if you enter something directly on Form IT-196 it overrides an entry coming from Federal Step by Step.
