Hi there, @rennik. I’ll be glad to assist you in sorting this issue.
With regards to your concern, you can delete transaction one at a time to remove data payroll as checks.
Before getting started, please make sure to secure a copy of your data files for backup purposes.
You can delete the paycheck by following these steps:
- Select Payroll, then select Employees.
- Select Paycheck list.
- Select the paycheck(s) you'd like to delete or void, then select Delete.
- Select Yes.
After deleting checks, you can set up prior payroll for QuickBooks Online. Moreover, you may check this article for additional reference: Delete or void employee paychecks.
Paychecks and check numbers can still be converted in payroll because this works as designed. For check numbers, it can be edited manually in QB Desktop.
Additionally, I’ve added these articles for more details about:
