Hi, brendan10.

Thank you for posting here in the Community. I can share some information about why payroll expenses getting duplicated.

There's a possibility that the payroll item was mistakenly added under the other tax upon setting up the employee's profile. You can check the transaction by running Audit Log Report.

Here's how:

1. Go to Reports.
2. Look for Business overview.
3. Choose Audit Log.

Once you verified that there is a duplicate item in the Audit Log. Let's delete it to fix the issue. Please follow the steps provided below.

1. Click the Payroll tab from the left menu.
2. Select Employees list.
3. Under Run Payroll, select Paycheck List.
4. Change the date range if necessary, and then select the paycheck you want to delete.
5. Click Delete.
6. Mark the tick box to confirm the deletion, and then click Delete Paycheck.

In addition, you can open a report to check the accuracy of your transactions: Run payroll reports.

I'll be right here to continue helping in case you have additional inquiries or require further assistance in managing your checks.
