How to set up proper text placement

How to set up proper text placement? In ads and on the forum, I place the text as I need it in a column, etc., but when I save it, everything is in one line.

It seems like a simple question, but honestly, I don't know how to solve it or where to configure this.  

Here, as I pressed enter, it went down and stayed that way, but mine is all in one line.
