Why am I being asked in "Personal" about occupation expenses (mileage, repairs, home office) when I already covered those for self-employment in the "Business" portion?

I already claimed my vehicle used for business, mileage, communications costs, software, etc., in the "Business" portion of TurboTax, so I don't know why it's asking me more of the same questions in the "Personal" section.  I am worried about accidentally double-dipping.
