Quickbooks was supposed to do a payroll correction and it has not been done. It has been a month. What should I do?

I'm here to ensure you're able to do payroll correction in QuickBooks Online, @nappymlp.

If you're referring to correcting employee information, here's a detailed reference on how: Add or edit an employee in Online Payroll.

You'll want to correct sales tax rates and settings. You may read through this article for more details: Set up your sales tax.

If you're referring to the adjustments that need the correction for payroll or taxes, I suggest reaching out to our customer support team. This way, they can further check and assist you in doing some payroll correction. 

I'm also sharing this page about employees and payroll taxes in case you need some additional reference.

I'm always here to guide you if you have other payroll concerns. Just let me know by adding a comment below. Keep safe.
