Should I leave the section of "Car and Truck Expenses Worksheet: Prior/AMT depreciation" as 0 as I do not how to acquire that information? Or would it be a problem?

I do know the definition of car depreciation but I do not know what I need to fill in nor where I can find that information. I'm stuck in the federal review section because of this and I cannot move on. Can I just put in 0 and would it be fine?
