I'm sorry ChristieAnn, your response isn't helpful as I've already called Guideline several times at the number on the website link you provided, and they have no clue what a payroll item or chart of accounts even is. They thought I meant the bank account, and kept telling me over and over that they withdraw the funds automatically from the bank account I specified and don't make an entry in Quickbooks, which I already knew.

Also, we have Quickbooks Assisted Payroll, so I don't need help setting up manual payroll in QBDT. 

What I want to do is update the account used for Guideline liabilities in the payroll item list. I can do this with every other payroll item, by right clicking and editing it. I can update the agency in my vendor list to whom the liability is paid, and the account in my chart of accounts that records the liability. I cannot do that with the Guideline-created payroll items and it's very frustrating to be told by Quickbooks that I have to call Guideline and to be told by Guideline that I have to call Quickbooks. 

The person at Guideline I spoke to yesterday had no idea what I was talking about (it's not her "wheelhouse") but that she would get back to me by email after checking with some other people. But I haven't heard back from her.
