Thank you for your reply.  I am not taking Sec 179 deduction or bonus depreciation.  I used a "Type" code of R on the asset entry worksheet, which I think is correct.  The software is showing the same depreciation for regular tax and AMT purposes.  If I override 200DB with 150DB at the bottom of the asset entry worksheet for AMT depreciation, the software still calculates the same depreciation for regular tax and AMT (using 200DB).
