Where do I deduct an improvement for a home office?

First off, I am using the Turbo Tax Deluxe installed on my computer, NOT Turbo Tax online.

I have replaced carpeting in my home office with hardwood floors. Based on what I have read, this should be categorized as an improvement rather than as a repair (because it increases the value of the home office space). But I don't see where to enter an improvement for the Home Office. There is a dialog where you enter expenses that apply to the home office and it includes an option for Repairs and Maintenance, but no option for Improvements.

Separately, there is an area for entering Assets and Depreciation for the business, but that seem to focus on equipment or other items purchased for the business, as opposed to something that is related to the home office space itself. I enter things like office furniture in this area, but somehow flooring, which cannot be moved if I change my home office, doesn't seem to fit in this category. But is this the only place where I can enter that expense?
