Please help me with handling of the Section 263a costs on Form 1125-A.  The client had Section 263a costs from PY that was on the tax balance sheet, but not on the books balance sheet.  Let's say PY Section 263a Costs adjustment was $20,000 which was reflected by increasing the ending inventory balance (not recorded on books, only on the tax return).  This year the S. 263a costs are computed at $30,000.

If I enter $30k on the Additional S.263a costs on the 1125-A form, it increased the COGS rather than reducing it.  What would be the right way to adjust for these costs from PY and CY.  I am planning to show the $10k difference as an M-1 adjustment as there are no plans to adjust the inventory amount on the books.  Any help will be greatly appreciated.
