Chord Sheet Maker Online was originally intended for "chords only" sheets, so adding lyrics alongside the chords is not well supported.
However, due to ongoing demand for this feature and the availability of several options to add text, I would like to revise my initial statement.
Yes, you can use the "literal text line" feature to add your lyrics alongside the chords.
But keep in mind that this approach clutters your chord charts somewhat, so I would still recommend using the "lyrics on an extra page" feature, which is especially powerful in conjunction with compilations.
That is very straightforward. There is a button lyrics edit which takes you to a form where you just add the song text.
The font size is automatically adjusted to the maximum size.
You can add page breaks by adding a + sign on a single line.
With this formatting it is possible, for example, to visually distinguish between verses and refrains.
Markdown formatting is enabled by default, but you can disable it in the settings.

You can choose between multiple text fonts in the settings.
Some fonts support more characters or even writing systems other than the Latin alphabet.
On a large screen you can display the lyrics sheet alongside the chords sheet.
That might be useful for practicing songs.
You can set your preferred order, lyrics-chart or chart-lyrics, in the general user settings.
See as an example Amazing Grace
If you add your charts to compilations you can create different variants of these.
See as an example a compilation of some Traditionals.
Despite the fact that literally every song's lyrics can be found in multiple places on the internet, it's not allowed to publish lyrics without permission from the copyright owner.
As a result, lyrics are only shown for some traditional (public domain) songs on this website.
But of course within your user account you can add lyrics as you like.
