By default, the report is not shown to respondents. You can change that using the “Show results to respondents” options in the survey Settings.
This points to the Standard Report, which cannot be edited.
If you want to show respondents a custom report that hides some items, you can create that and copy the Report URL from its Publish page.
Then you can go back to the survey Settings and paste that URL into the Redirect Page field, after deactivating “Show results to respondents”.
