- Then click on jump to home office, self-employed (this may revert to jump to schedule c and then click it, if so)
- Click Edit next to your business you have listed
- Scroll down to Home Office Expense and click Update or Start
- Go through those questions (make sure you answer them correctly) to input everything about your home office.
- You will eventually come to page where it says How big is this home office? and that is where you will input office square footage and entire home square footage
