AMT Prior Dedreciation

[Porsche993]

Under Check This Entry, TT is asking me to fillin the AMT Prior depreciation.  So where/how do I calculate this requirement?

Thanks,

Ken

If you have never been subject to AMT, the amount will be the same as regular depreciation. If you have been subject to AMT, you can look back at your AMT on Form 6251, line 2L. Dependent upon what you are depreciating, you may not be subject to AMT. Please see which items require adjustment versus those not required here.
