It's possible that the scheduled tax payments were set up incorrectly that's why the Period Covered displayed inaccurately. Let's review the scheduled tax payments list to ensure it's accurate and have some changes if needed.
Go to the Employees menu, then select Employee Center.
Select the Pay Liabilities tab.
In the Other Activities section, click Manage Payment Methods.
Go to the Schedule payments menu.
Review the description of each payment, and click Edit if there is some modification needed.
If the information is accurate, I'd suggest contacting our Phone Support Team. This way, they can further investigate the issue and provide additional troubleshooting steps to get this fixed.
