Investors & landlords

Thank you Diane! If I'm understanding correctly, the total square footage of all our offices is combined is under 50% of the home's square footage. Therefore it's under 50% business use, so I can't take the Section 179. So exactly where in Turbo Tax do I enter this roof depreciation? I need help being walked through to get to the spot to enter the cost.  Is it in the Business Income & Expenses section and I'd select the name of each business and enter it in each, one at at time? When I'm inside a business, is it Business Assets (business property that is depreciated)? OR is it Home Office Expense? Or is it somewhere else?  I'm lost. ðŸ¤”
