Hello there, @ccbookkeeping.
I appreciate the details you've provided. I can help you correctly set up the WA Paid Family Medical Leave in your QuickBooks.
To begin, let's verify the set up of the tax item under your employee's profile:
- Click Employees.
- Choose Employee Center.
- Double-click the employee name.
- Choose the Payroll Info tab.
- Click Taxes.
- Choose the Other tab.
- Highlight the WA Paid Family Medical Leave item.
- Make sure that the Rate is 100.0%.

After running through your employee information, download the payroll tax table update:
- Click Employees.
- Choose Get Payroll Updates.
- Select the Download entire payroll update radio-button.
- Click Update.
- Wait until the download is complete, and click OK.

Then, try creating paycheck once more. If the paychecks are highlighted into yellow, you will have to revert the paycheck to refresh the calculation.

That should correct the calculation of the taxes on the paychecks.
Keep me posted if you have other concerns about payroll. I'm willing to provide more help. Wishing you all the best!
