In my opinion, this is a TurboTax Software issue - the instructions are far from clear - in the Home Office Deduction Section it specifically states "We're looking for Frank's total expenses for the home here, not the home office." - I ended up with a smaller than expected State Refund due to double credit for Property Taxes paid - I use TurboTax for the "step by step" guidance > it shouldn't be up to me to know the assumptions the software is making.
