That specific line is not hyperlinked like others are. I do have a simple balance sheet which is cash plus a few depreciable assets.
That line 10 seems to come from the difference BOY and EOY shown in "Net assets/fund balances at end of year" on the Federal Exempt Organization Tax Summary, which is supposed to equal Form 990 Part XI line 10. It did on the 2018 return, but it does not in the 2019 return right now. So I need to recheck all expenses and balance sheet items. It is off by the amount of net assets at BOY for some reason.
They converted to QuickBooks from an Excel spreadsheet that was basically a checkbook in 2019. There was a minor difference in the roll of tax assets, so that might be one of the issues causing this.
