You will use the TurboTax self-employed if using the online version (which approx. 80% use).
If you use the desktop/CD you would use the TurboTax Home and Business as this has the detailed questions, for a Sch C, business.
The Realtor income and expenses will be reported on teh Sch C which is part of the tax return.
