What to enter for prior depreciation equivalent and AMT prior depreciation equivalent when calculated amount is greater than cars value when put in use

I had a low value car, put a lot of miles on it, and last year turned it in for scrap metal. The depreciation value I calculate by the guidelines is near twice what I estimate the car was worth when put in use, turbo tax says not to enter an amount over the value of the car but insists I enter an amount for both prior depreciation and AMT prior depreciation. What then do I enter, and would I enter the same amount for both?

Yes, enter the total original value of the vehicle in both the Prior Depreciation and AMT Prior Depreciation boxes. Since you cannot claim more depreciation than the cost/value of the vehicle when you began using it, you are limited to that number when reporting the sale/disposal.
