Is it worth upgrading to Turbo Tax Self-Employment. I have an active real estate license but not actively selling anymore. My intent is to make money on the side.

A Schedule C for your business should not be filed unless the activity is done with the intent to produce income in the current year. Expenses are deducted in the year they are paid for cash basis (the most common basis of accounting for small businesses) businesses.  Next year if you are operating with the intent to produce income, you should file a business return and you can deduct any expenses you have for that tax year.
