I entered a check into my savings account How do I cancel it?

Hello, @mkronerc. I'm here to help you cancel a check.

In just a few clicks, you'll have the check removed from the savings account in QuickBooks Online. Here's how:

1. Go to Expenses on the left-hand menu.
2. On the Expenses tab, press on the Filter button.
3. In the Type field, choose Check. 
4. Select the date range, then Apply.
5. From the Action column, select Delete/Void from the View/Edit drop-down menu.
   • Delete: this removes the transaction entirely from QuickBooks.
   • Void: this changes the amount to zero and keeps a record of the transaction.
6. Press Yes to confirm.

That's all there is to it! 

I'm here if you need anything else. Have a nice day.
