Are Section 179 deductions counted as accumulated depreciation for form 1120 form L line 10b?

[Mike9241]

all prior year depreciation including sections 179 and 168(k)  and current year depreciation.  however, if you use different depreciation methods for book and tax then schedule L reflects book depreciation.

depreciation can show up on line 20 of page 1 and/or lines 4 and/or 5 of form 1125-A.
