@Charies_Mthanks for your reply.
I set up payroll from scratch as I didn't activate it straight away when I migrated to QBO (I used QBO without payroll for a while) - I didn't expect to import all of the same data. I don't believe I need assistance with any migration information.
It is simply that it isn't clear how QBO payroll (standard version although I think I need to upgrade to Advanced) processes payroll liabilities. I can't find this data anywhere and so can't report on it.
I have received conflicting information saying I have to manually input it (which is ridiculous) and other information saying a journal is created and so the information should be there.
