Where are you see the 179 deduction? On the depreciation Schedule? i.e. 179/SDA? or are you seeing in on the Form 4562, line 6 or are you maybe seeing it on line 14?

You really need to make a concerted effort to get 179. You must make an entry to get that.

You really need to make a concerted effort NOT to get SDA. You must make an entry to make it go away.
