These expenses flow to the Schedule A on Line 6, Real Estate Taxes and Line 10, Home Mortgage Interest. If your total deductions reported on Schedule A are less than your Standard Deduction, Turbo Tax will maximize your deductions and claim the Standard Deduction.
Since you saw no change in your refund when you added the deductions, they were most likely not in excess of your Standard Deduction amount - especially since you are deducting some as Home Office expense.
You can find the Standard Deduction chart at the link below on page 25
