Hi there, @javierehb.
I can help walk you through the steps on how to delete and re-process payroll in QuickBooks Online.
If you're using Direct Deposit in processing payroll, you can delete the paychecks if the payroll status is not yet processed. See the sample screenshot below:
Here's how to delete:
Once done, recreate them. However, if this is already processed, Intuit unable to stop the direct deposit transaction. Please note that processing payroll depends on the funding time set-up in the account. For more information, check out this article: View or change your direct deposit funding time.
On the other hand, if you're using checks, you can delete it anytime and re-create it.
