Hi Sandra
You do this in Accounts (not Entries) e.g. for an account called "Barclays" in Accounts, move to its right a couple of inches and then:-
1. Double-click on its balance in either Statement or Current or Forecast and an auto report will spring up and then...
2. In that auto report, either click on its summary button at bottom left or right-click and select "summary" from the drop-down menu and another auto report will spring up showing monthly totals.
Both types of report are shown about half way through this video:-
