I HATE QB online.  It is terrible for accountants.  Doesn't have near the capabilities as desktop.  Now I see you cannot adjust payroll liabilities without calling them.  What a complete waste of my time, when I can do it myself.  If they make everyone switch to online, I will find something else and take all my clients with me.  I have heard that they will keep Enterprise on desktop, so that may be the only route to not got to QB Online.  

Same problem here. Was on the phone for 2+ hours and transferred to several different people and no resolution. Payroll liabilities simply need adjusting and nobody has an answer. Unreal.

This was frustrating for me, too, but it's actually very easy to do. Just turn off the automated taxes and forms feature and then you can make any necessary journal entries to adjust your liability accounts. You can turn it back on when you're finished. To turn off the automated taxes and forms feature, go to Payroll > Payroll tax from the side menu. In the upper right corner of the screen, you'll see Automated taxes and forms: On. Click the Change Setting link right below that. Scroll down to the Taxes and Forms section and click the pencil icon on the right side. Uncheck the Automate taxes and forms selection and Save. Now you can access your payroll liability accounts in the journal entry screen and make whatever adjustments you want. Once you're finished, turn the automated taxes and forms feature back on and everything will be correct. 

Still on Desktop here, but are you seriously telling me this is not a feature available after YEARS of complaints?  I will NOT be forced into an inferior product, and neither will my clients.
