Why is there a "Depreciation and Section 179 deduction" on my MA state Schedule C return?

Where does the amount for Schedule C Line 11 "Depreciation and Section 179 deduction" on the MA State return come from in Turbotax?  I cannot trace this back to my Federal Return and it causes my MA and Federal Schedule C Net Profit to be different.

 

My MA state return shows a depreciation adjustment of $10 on an activity worksheet.  It causes a Federal/State adjustment of $10. I was never prohibited from taking a full Section 179 deduction in prior years and there is nothing in the Federal worksheets or depreciation tables that I can trace this back to.

 

How can I determine what is causing this adjustment in Turbotax?
