AMT depreciation report for rental property shows prior depreciation to be zero

[TaxNewbe]

I have been using TT for many years and always transfer the return from previous year. It does transfer the data but, I have noticed that in Form 4562 (Alternative Minimum Tax Depreciation Report) the "Prior Depreciation" column always has a "0" for all last 5 years' returns. Is it normal or have I been doing anything wrong?

Generally,If you make all the required entries and the program doesn't display an amount in this field, it's because no AMT recomputation is required.
