Where has the menu option for accounting gone and how do I get to it? I am using quickbooks online and I am in accounting view.

Hello accounts566, thanks for joining the Community 

With the new One Navigation menu, the Accounting section (comprising of Chart of accounts and Reconcile) can now be found grouped under Transactions. 

If you have any feedback on the new view, please submit this via the in-product tool (Cog > Feedback).
