Hi @Cristi_Jayo! 
What you are saying is correct. The indent and outdent options appear after you create bulleted and/or numbered list. The reason is that indention is specific to lists.
If what you want is to indent the paragraph, I would recommend that you use the spacebar to add the indent you need.
You can read more about text formatting in the following article: How to Format Text in Asana • Asana Product Guide
I hope this helps! Have a great Thursday!
