I have a home office and a shop. Where do I input costs for the shop (which are at 100%) so they are separate from the home office (which is less than 10%)?

In TurboTax Self-employed Online there are a few different Expense categories that you can use:

 

Commercial insurance - Premiums for insurance on buildings and equipment

 

Repairs and maintenance - Labour and materials to maintain a business property

 

Property taxes - Property tax for a business location that is not your home

 

Utilities for business property - Utilities for a business property that is not part of your home
