I called Support and was told that I had two choices
1. Fill in the Allocation Percentages on Screen 34
2. Once you have manually input the Depreciation amount in the appropriate column and the critical Diagnostic changes, go to E-File pull down menu, choose E-file Support Tools, choose Disable E-file Error.
What worked for me was to leave all the amounts I manually input and then put "1" to represent 100% under Management and general in the Allocations Percentages section. The diagnostic went away and the depreciation filled in under Mgmt/General as I originally intended.
