Start with your profit and loss beside a drilldown pane. Keep the big picture visible while you investigate.

Click an account amount. Its supporting transactions appear right beside the report.

Choose the columns you need for your review. Here, we hide the transaction ID to give the useful detail more room.

Move to the next account. The detail pane updates, and your column choices carry across.

Save the setup as a named view. Saved views belong to this browser and this QuickBooks company.

When you identify a correction, open the account drill in a new tab, turn on batch edit, and select the relevant lines.

Choose the field to change, preview the proposed update, and apply it once the changes are correct.
