I primarily work as a W2 employee as a nurse practioner, but I am a real estate agent on the side. I want to make sure I am filing correctly.

Since you receive a W-2, that income would be personal income, unrelated to your Schedule C for self-employment as a real estate agent.  Your real estate expenses would be deductible against your real estate income.  Your nurse expenses, if any, would be deducted as job related expenses under Deductions and Credits.
