Plasterboard meets flying lamp

[Sabatinitennis]

I have a newish home, so plasterboard walls (magnolia) I guess. I reached out and knocked my bedside lamp from its perch on top of a cabinet and it fell against the wall and bounced between said cabinet and said wall and has gorged and marked the plasterboard four times.
What is the best filler to use to fill in the four grooves that I now have in my plasterboard walls please?

I have recently started using Toupret powdered based filler on similar plasterboard cracks and holes. It needs mixing but with care leaves a fine sandable finish.

Obliged.
