Hello there, @whyknotunwind.
Thanks for visiting the Community.
The reason your quarterly state tax form information didn't match because your payment may be assigned in a wrong period.
If your payroll liabilities are incorrect, you can use a liability adjustment to fix the issue. Let me guide you on how.
Here's how to adjust for the company:
1. Go to the Employees tab and select Payroll Taxes and Liabilities.
2. Click Adjust Payroll Liabilities and then select the date on which you want the adjustment.
3. Now select the Effective Date for the adjustment.
4. Select Company under the Adjustment is for a segment.
5. Now choose the adjustment item from the Item Name drop-down list.
6. Enter the negative amount that you have paid for the adjustment.
7. Type your explanation for the transaction in the Memo section.
8. Hit the Accounts Affected button.
9. Click Affect Liability and Expense Accounts if you want your accounts to be affected or else choose Do Not Affect Accounts.
10. Hit OK on the Affect Accounts screen.
11. Click OK again to save the adjustment.
If you're doing adjustment for the employee, please follow the steps.
1. Follow step first to third from the Adjust your Company method as given above.
2. Select Employee under the Adjustment is for a segment.
3. From the drop-down list, click the employee’s name for which you want to make the adjustment.
4. From the Taxes and Liabilities section select the payroll item for adjustment and enter the negative amount.
5. Follow steps 7 to 11 as mentioned in the Adjustment for the company method to save the changes.
