At the start of filing, it would seem that I selected Expert Review... and as I have progressed through the process, I did not use that service. How do I remove it?

I am filing for 2022 for myself and spouse.  I expected that at some point later I would have the opportunity to confirm the service levels, ie. Expert Review, Audit etc.  

Getting started

You can't downgrade. You will have to start a new return if you don't want to use Assist & Review.
