Free fillable forms is hard to use for taxes in general, but this page is specifically for people who want the CTC without having filed taxes (presumably you otherwise would have gotten the CTC when you filed takes). You can see the screenshot says "non-filer sign up tool", where as the main page of the website (for people who want to actually use it to file taxes) has no such warning: https://www.freefilefillableforms.com/#/fd
