Bruce, thanks for reaching out. Let me add some insight.
When you have sub-accounts of income or expense, and do not record an income or expense to one of the specific sub-categories those transactions are all grouped and reported as "Other". For each partcicular nexted category there will only be one "Other" account reported. You can reclassify items to get them into your sub-accounts and reduce or eliminate any "Other" transactions.
Now, specifically to rentals in partnerships. Your P&L from rental activity will be reported on a form 8825 (similar to Schedule E used for individuals, but for partnerships). There is only 1 income category, which is Gross Rents. All expenses are below the line in the expense categories. Thus, even though in your QB books, you might have multiple income accounts that generate money from tenants (such as late fees, eviction judgments, application fees, parking space charge, etc) you would group all of those on the 8825 as Gross Rent.
Other property income, such as laundry or other service fees should probably end up on the 1120S in the business area. This is also where you would place any expenses that are not property specific, which could include interest payments to partners that you do not allocate by property. Just one example.
There may be in the end income and/or expenses that are not on the 8825 but instead on the 1120S and other than rental profit you could have a loss in that section
