Question about USACO testcases

When I’m practicing a problem, and I get test cases incorrect, tle, etc. How do I see the test cases, clicking on the red squares doesn’t work. Is there even a way to see the input test cases? Note I am practicing on problems, NOT competition. Confused as hell, because when practicing on Codeforces I can directly see the test cases and the problem input.

Click “return to problem list” (top right). Find your problem in the list and there is a link to download all the test cases.
