941 error - Total taxes after adjustments does not equal the total quarter liability on page 2

Good to have you back, McMillanClerk.

Fixing the tax amounts on the 941 can be a bit tricky, so I'd like to extend a helping hand and point us to the right direction to ensure we can fix the discrepancies. 

Submitting that $504 amount might cause more discrepancies on the next period. So, if you've confirmed that the payroll checkup reports the discrepancies correctly, then we would need to fix that to avoid more adjustments (and hefty penalties) on the next tax period. 

We're on the right path in correcting the amounts in your 941 form. We would just need to use the Adjust Payroll Liabilities, then select the Affect liability and expense accounts option to adjust the amounts on the payroll items or accounts with the discrepancies (as outlined in your PDF). 

To summarize the steps from the article: 

1. Go to the Employees menu, then hover on Payroll Taxes and Liabilities.
2. Choose Adjust Payroll Liabilities.
3. Select the Effective Date (for the current tax period for the 941). 
4. Click Employee Adjustment.
5. Select the affected employee from the drop down list.
6. Under the Taxes and Liabilities section, click the Item Name column. Then, choose the payroll or tax item (we can follow the PDF to look for the accounts affected). 
7. Enter the amount of the adjustment in the corresponding column. Negative to decrease and positive to increase. Enter a Memo if needed. 
8. Click Accounts Affected, then select Affect liability and expense accounts.
9. Click Next Adjustment button at the top if you want to adjust another employee. When you're done, click OK to save your changes.
