If I used standard mileage deduction for first year, then switch to actual expense in the following year, do I claim "no depreciation" for the first year?

During the Error Check, TT tells me that on Schedule C... "Car & Truck Expenses Worksheet: AMT prior depreciation- 1 must be entered. If none, enter zero." (attached is a screenshot).

Then it gives me a box to fill in the AMT prior depreciation. 

Where do I find that figure? My total standard mileage deduction for the car in the previous year was $876. 

I'm using TurboTax Home & Business
