Payrun accidentally deleted for this fortnight

Thanks for taking the time to post here in the Community, Ellice20.

Deleting a pay run can't be undone. You'll want to recreate it to proceed with adding employees to the pay run. You can check out this article for your guide about creating a new pay run: Create a New Pay Run on QuickBooks Online Advanced Payroll

I'm also including some articles related to pay-run in QuickBooks Online for your guide:

• Manually adding and removing employees from a pay run in QuickBooks Online Advanced Payroll
• Unlock a pay run in QuickBooks Online Advanced Payroll

Please let me know if you have any other concerns. I'll be around to help.
