If you added improvements to your whole house (e.g., a new roof), you would add a new asset to your business (if self-employed) or your employee business expenses (if this is a home office for your W-2 job). Do this in addition to the depreciation you're already claiming on your house.
As you're entering the asset following the steps below, be sure to say that this is "non-residential real property" and say that you use the asset the same percentage of business use that you do for your typical home office. For example, let's say your home is 2,000 square feet and your home office is 200 square feet,
so your office is 10% of your home. That 10% will be the percent business use of your new asset (the improvement).
For an employee, do this:
Enter your new asset under the Personal tab rather than the Business tab. If you're entering them under "personal," then they are for W-2 employee expenses rather than Sch C self-employed expenses.
Click on Income & Expenses, then Deductions & Credits, then scroll down to Employment Expenses and select Job Expenses for W-2 Income. Then follow the prompts.
You'll eventually come to the screen asking Did you buy or own any items for use on your job. Check "yes" and that will initiate the asset screens for depreciation, where you can tell TurboTax what you bought and all the particulars.
To enter the new asset as self-employed:
You
will depreciate the improvement as a business non-residential real property
asset over 39 years.
