Thanks for adding more details about your concern, SaraBee.

As mentioned by my colleague, recreate the code, and enter the correct one. This is to ensure you can enter the correct date. Then, perform a manual adjustment to keep your payroll records in order. 

We’ll have to do this per employee to get an accurate amount. Also, the new rate will automatically apply to future payroll.

To start, pull up the Payroll Summary Report and select a per quarter date range to get the accurate amount for the employees affected. Here's how to open it.

1. Go to the Reports menu at the top and choose Employees & Payroll to select Payroll Summary.
2. From the Dates drop-down, pick the specific quarter
3. Hit the Refresh button.
4. Next, click the amount for the payroll item beside the worker's name to see the complete details.
5. On the Transactions by Payroll item page, navigate to the Wage Base column and take note of the total amount.
6. Then, multiply the Wage Base amount to the rate.    
7. Continue performing this process to all the employees you’re working on.

Once you have all the information, you can start creating liability adjustment. Here’s how:

1. Tap the Employees menu and pick Payroll Taxes and Liabilities to select Adjust Payroll Liabilities.
2. In the Liability Adjustment window, use the same date as the last paycheck of the affected quarter. Otherwise, enter today's date if you’re working on the current quarter.
3. The Effective Date is used to calculate amounts on your 940 and 941 forms as well as the Payroll Liability Balances Report.
4. In the Adjustment is for section, tick the box for Employee and choose the worker’s name from the drop-down.
5. In the Item Name drop-down, pick Workers Compensation and type the adjusted figure in the Amount column.
6. Click the Accounts Affected button to choose any of the following:
   •Do not affect accounts to leave balances unchanged for the liability and expense accounts. The adjustment will only change the year-to-date amounts on your payroll reports.
   •Affect liability and expense accounts to enter an adjusting transaction in the liability and expense accounts.
7. Hit the OK button and press Next Adjustment to continue.
