Deductions & credits

I don’t understand why it would take a long time to enter the standard mileage method, the only facts that are needed are the total business miles you drove for the year. You certainly don’t need to list every single trip. You need to have those records available in case of audit, but they are not reported on your tax return. Even if TurboTax allows entry of individual trips, only the final total is reported to the IRS. 

The IRS suggests that the standard mileage method is more generous for the majority of taxpayers, although that will depend individually on if it is a new car you are making payments on, and how much your insurance costs are.  For an older car, the standard rate will almost always be better because you can continue to take a depreciation allowance that is built-in to the standard mileage rate even after the car would normally have been fully depreciated using the actual expense method.
