Okay, my first response was mostly wrong.

If it QUALIFIES for Bonus Depreciation (even if you elect out), you use 200% and there is no adjustment.

If it does NOT qualify for Bonus Depreciation, you use 150% and there will be an adjustment.

From the 6251 Instructions:

Qualified property that is or was eligible for a special depreciation allowance if the depreciable basis of the property is the same for the AMT and the regular tax. ... If you elected not to have any special depreciation allowance apply, the property may be subject to an AMT adjustment for depreciation if it was placed in service before 2016. It isn’t subject to an AMT adjustment for depreciation if it was placed in service after 2015.
