Let me share some insight into the trial balance report in QuickBooks Online (QBO).
The trial balance is a financial report that is generated at the end of an accounting period, before the creation of your financial statements. This is to allow you to recognize any accounting errors and make adjustments so that your financial statements are completely accurate.
To write off a debit, we can create a journal entry. However, I'd also recommend seeking assistance from your accountant so you'll be guided with the correct posting account to use.
