If you're self-employed, you can enter your union dues as a Schedule C business expense.
Otherwise, if you're an employee, enter your union dues as a job-related expense. Simply search for union dues in your TurboTax program and then click the "Jump to" link in the search results. We'll take you to a screen that asks about your job-related expenses.
Very detailed instructions on how to enter your dues are on the link below.
