I do appreciate the response, but as I've said multiple times in this thread, I do not use Quickbooks Online Payroll. I used it for a while with another client, but had several serious problems with it and moved on to a different payroll provider.

Even if you were to send the correct link it wouldn't help because I already know how to set up and run payroll and manage payroll items. No amount of documentation will get me past the fact that I cannot edit Guideline payroll items, because I get a message that these items are managed in Guideline, and Guideline tells me they have no control over how payroll items are managed in Quickbooks. 

I'm reluctant to reach out to QB support again because it's an ordeal just trying to get to the right person who is trained on QB desktop assisted payroll. When I do finally land on someone who's knowlegable, I do a screenshare with them and they tell me I have to contact Guideline because obviously these items can't be changed in Quickbooks.
