Hi @demonslayer112 ,
see the first two answers; the confusion is because of the naming.
Just use Annotations for what was called Grease Pencil before 2.8. It is mostly the same; the only thing you can’t do with Annotations, is Convert it/them to Curve(s), which can then be Converted to a Mesh…For that, you’d have to use 2.8+ Grease Pencil.
