Hello, I didn't generate any income for my home business last year, how do I claim my home office expense?

You still claim it as a business expense and that gets reflected as a business loss, effectively creating a credit to the owner.

Thanks! However Turbo Tax is still asking to enter my 2018 income via 1099 forms in order to estimate the business expense. There is no option to choose "no income in 2018". :( Please help.
