If you lowered the amount of business usage for the asset, that is usually when you receive this error message, because you have taken more depreciation than is allowed if the business usage is less than in previous years.
If this is the case you would need to know how to calculate the amount of depreciation allowed due to the change in business usage.
AMT depreciation is a separate way to calculate the amount of depreciation you can take. Under Alternative Minimum Tax (AMT) the amount of depreciation you are allowed to deduct is lower. You would use the AMT Depreciation if you have to recalculate the tax due on your return if you owe AMT tax. In your tax return there is a separate depreciation schedule showing the amount of AMT depreciation that is allowed.
