The last I saw (which as been quite a while, so it may have changed), you enter the information based on calculating the Standard Mileage Rate and it tells you the amount, then it asks if you want to try to enter Actual Expenses to see if it is better. Is it not asking that?
For the business percentage, go back through the questions and look for the one that ask if you kept track of personal miles. Say YES to that question.
