I am logged in as the Master Admin account and the only user on the account, so I don't believe this is a user permissions issue, and I don't think I can "remove and re-add" myself.

I continue to see the same lack of a "Filters" section on the Customize section of P&L.

I suspect that the problem is that I'm on the Simple Start plan and that I have to pay Intuit more money in order to get access to necessary features.
