I got carbon fiber Twill Weave 200gsm but it came folded, does anyone have a good tip on how to remove the marks from the fabric?

Yeh unfortunately it will likely always be visible. You can move the fibres around by hand and try to pull them back as straight as you can. Will be fine for smaller parts, but I wouldn't use it on large flat panels like a bonnet as you will very likely see the distortion.
