You could put the content inside a 3-column table or you could set a "hanging indent"

If you have a lot of text written already where it wraps to the beginning of the next line, you can convert your text by going to the ribbon and choosing INSERT, Table, convert text to table, or you can create a new table that is 3 columns wide.

Alternatively, you can set a hanging indent by right-clicking on the text, choosing PARAGRAPH, and where it says "none" choosing "hanging" and set it to 1.5 if you haven't set up particular tabs.
