I am using the installed version of TurboTax Home and Business. I am trying to enter information on a home office. I used the office only for the first six months of the year, then retired. Do I enter the expenses (mortgage interest, utilities, etc.) for the entire year or only prorate for the six months of the year when I used the office?
When I entered the entire year's expenses, TurboTax askes how many months I used the office, but calculates the same deduction whether I enter 12 months or 6 months or even 1 month.
