trying to smooth simple chamfer

complete noob at this.   Running Blender 4.4.3.

I set segments to 4 then created a cube and chamfer.  I want to have smooth curve.  ChatGPT Blender Buddy says to:

• Go to the Object Data Properties tab (green triangle).
• Enable Auto Smooth under Normals. 

I don't see Normals.  I see Color Attributes, Attributes, then Texture Space.  My understanding is that Normals should be under Attributes.
Where is Normals?  Is this the right way to do this?
Want to keep my poly count down
