From the main screen, select BANKING SERVICES (near the bottom) on the column to the left.

A pop-up menu will open and select QUICKBOOKS CHECKING.

At the top it will show your Total Balance and 4 circles to the right: select MANAGE.

This page will show all your account info, i.e. account number, routing number, etc. 

From there select MONTHLY STATEMENTS. 

Not very "intuitive" but there it is.
