I have now checked the "display 'difference' amounts on schedule M-1" and removed my manual entries from the the actual M-1.  Should I still leave the data in the Schedule M-1 Smart Worksheet blank?  The M-1 is still not showing data.

One thing I should mention.  All of the partnership's income comes from 4 other partnerships.  I've entered all the K-1 data for those 4 partnerships, but the  Nondeductible Expenses from Box 18 Code B and the Other Tax-Exempt Income from Box 18 Code C of the K-1s don't carry to lines 18b and 18c of the Schedule K.  All of the other data from the K-1s does carry over to that Schedule.  Could that have anything to do with the issue I'm seeing?  I notice that Schedule I does not have a "From K-1s" column for 18b and 18c, (as does 18a).  I thought maybe this was something that I should manually enter on the M-1 Worksheet, but it only prompts for "Per Books" entries.
