Thanks for your response.
When I follow those instructions, I get a pop-up "Warning" that says, "You're attempting to edit an e-payment that has already been submitted. you cannot edit the Vendor, Amount, Withdraw On, or Payment Reason fields on a submitted e-payment."
If I try to adjust the amounts (that need to be split three ways) it automatically reverts back to the way it was. If I try to select the account in the Payroll Item field, to divide the amounts into three, the warning message pops up immediately and I can't do anything.
I've also tried to do a manual Journal Entry to make these adjustments, but that did not work either, as I got a message that I could not make a journal entry to change a liability account.
