QB Mac 2019 payroll error. My 401K contribution is showing as a company contribution rather than an employee deferral. Can I make the change even though this was 2 months ago.

Hi @rmacdonald004,

You can create a liability adjustment to resolve this specific situation in QuickBooks Desktop (QBDT).

What you need to do first is to find out the discrepancies. There are two things you can do to help in this process:

• You can run a Payroll Checkup.
• You can also create a payroll summary report.

When you're ready to proceed with adjusting your payroll liabilities, follow the steps below:

1. Go to the Employees menu.
2. Highlight Payroll Taxes and Liabilities.
3. Select Adjust Payroll Liabilities.
4. Choose the employee in question.
5. Complete the Taxes and Liabilities fields.
6. Tap Accounts Affected, then OK.
7. Repeat the same steps for other employees if necessary, then hit OK.

See this article for additional information: Adjust payroll liabilities in QuickBooks Desktop. Scroll down to Step 3: Make sure your liabilities are updated to continue. 

In case you need to edit the year-to-date additions or deductions, you can take a look at this article: Correct year-to-date (YTD) additions or deductions on a paycheck when the wrong tracking type was us....
