I'll help you find the reclassify transactions feature in your account, @GABC LLC. This way, you can reclassify your various data as soon as possible.
The ability to reclassify transactions is exclusive to QuickBooks Online Advance and Accountant. If you have this subscription, you'll find it under the Gear icon or Accountant Tools.
If you're using a different version, the only way to reclassify transactions is to edit manually. You can go to the Sales, Expenses, View Register, and Banking windows to modify and open the transactions one at a time.
