Hi there,
Glad to have you join the QuickBooks Community. I'll be glad to steer you in the right direction so you can get the resolution you need in a timely manner.
To make sure I'm on the same page as you, could you elaborate more about the goal you're looking to accomplish? What happens when you try to modify the payment history for the employees? Feel free to share with me the steps you're following on your end.
I look forward to hearing back from you. I'll be a message away.
