Whole Home vs just Home Office expenses

[Jeff1979]

In Home Office Expenses section, there are 2 screens asking for 'entire home', and 'home office only', expenses.  When TurboTax refers to 'home office-only' expenses, is it asking for "unique" expenses over and above 'entire home' expenses?  Or, is it asking for some "subdivision" of 'entire home' expenses?

Can you post a screen shot of the screen you are questioning?    Your home office business deductions are based on either the percentage of your home used for the business or a simplified square footage calculation.   TurboTax will first determine the percentage of business use from your home and then apply those percentages to the total expenses for each category.   Example- TurboTax determine your office is 10% of your home.  You enter your annual costs of running the home and TurboTax should apply 10% of those costs to your home office deduction.  

When you enter your home office information in TurboTax, we'll ask some questions to determine if you can claim the deduction and how much the deduction is worth. You’ll need information like the square footage of your residence and the rooms you worked in.    Check your Form 8829 before you file to ensure only your home office amounts are deducted on your Schedule C.

When TurboTax refers to 'home office-only' expenses, it is asking for "unique" expenses not reported elsewhere for the HO. such expenses could be like a dedicated phone line, office supplies, small equipment, etc.
