After you file

Even if it's my own personal vehicle? The TurboTax website does allow for auto mileage to be deducted - which I have entered, and was given a deduction amount on that specific page. That amount does not appear when I reach the end of the filing process. I learned of the deductions for auto mileage, or fuel receipts, through co-workers who have deducted in the past, and have filed the same way this year. So now my confusion is even more than before.
