They would go in the sections for 401ks and IRAs just like they do on the paper forms. The online form will have the same way to enter the additional deductions.
They should (and do?) have the same information your employer, bank, or brokerage files. i.e. the same forms you use to fill out your taxes now. They know what you contributed to you 401k and your other retirement accounts.
Solo 401ks are where you’re the employer (guess technically there’s some wiggle room for others to be in your 401k, but from the perspective of such a person, wouldn’t it just be a normal 401k?). So you have to report it yourself. The brokerage firm holding it won’t.
Solo 401ks/IRA also wouldn’t be something they know about until you file if I understand correctly. Guess you could that expenses?

Well, yeah. If you’re self employed, you have to report yourself too.
