How can I delete and or edit duplicate paychecks i wrote in January of 2020 that has upset my QB online balance?

Good day, @Ospreybob.

You have the option to delete or void the duplicate paycheck. Just a heads-up though, you can remove the check on or before the due date of your quarterly forms, which is April last day. 

Here's how to delete a paycheck:

1. Go to the Workers menu.
2. Select the Employees tab.
3. Choose Paycheck List under Run Payroll,
4. Change the date range if necessary. Then select the paychecks you want to delete.
5. Select Delete.
6. Mark the checkmark box to confirm the deletion.
7. Click the Delete Paycheck button 

Meanwhile, here's a screenshot of how to void your duplicate paycheck:

Welcome to the QuickBooks Community, @Doris G.

Allow me to share some insights about your concern. Not able to see the Delete and Void option means that your account is one of the affected for the ongoing investigation (INV-42713).

To be notified of the updates, I suggest contacting our support team to add you on the affected list. There will be an email confirmation once the issue is fixed. To contact support you can follow the steps provided by, @IamjuViel.
