Yep, that's the right place. Here's their definition for hand-cut cards to get a number grade: "In order for PSA to actually assign a grade to any of the cards that possess visible/defined borders on all four sides, evidence of that border must be present or the card must exhibit virtually-full borders based on the design of the specific issue. If the cut exceeds the visible border for the card in question, PSA will encapsulate the card as "Authentic" only. If the card is severely undersized and suffers in overall eye appeal, the graders may deem the card not suitable for authentication or reject the card as minimum-sized altogether."
Basically, you need to have all the black borders showing on cards that have them. This may mean cutting into a less valuable card to get a full sized more valuable card.

Here's one that was probably borderline for getting a grade, but every side has a sliver of the black border. But you're probably better off cutting it like this:
