I'll make sure QuickBooks Online displays the right information to keep your account accurate and up to date.
When income accounts show as negative, it indicates a credit. While expense accounts are reported as positive, which specifies a debit.
You can pull up the Profit and Loss Detail report and add the Credit and Debit column to check your accounts.
Go to the Reports menu.
Type Profit in the search box, then select Profit and Loss Detail.
Select the Gear icon at the top of the report.
Click the box beside Credit and Debit.
Select the Run report button.
I've attached screenshots below for your reference.
If you wish to save the current customization settings of the report you've pulled up, you can check out this article for the detailed steps: Memorize reports. It also contains information on how to send reports by email on a recurring schedule.
