I'VE FOUND OUT! This took literally hours of frustration.
Basically just fill in all the information for your parents anyway (doesn't have to be true, you're going to delete it in a minute), and when you've done all that and reach the "Submit application" page, it will give you a link to click saying "Alternatively, apply for a non-means tested loan". Then just click on that and you can start from scratch.
