Getting back to Kerbin

[thesigmagamer]

So I'm brand new to the game and loving it, but a tad confused. This is my current trajectory: https://imgur.com/a/APg1p . I'm not quite sure how i can see the orbit I would have around Kerbin but my current trajectory is into nowhere, despite my attempt at following instructions. Any advice?

The orbit that you'll have around Kerbin after leaving the Mun's SOI, is represented by the dotted purple line on the right in your image.

You'll want to bring your trajectory more parallel with Mun's orbit for the most efficient return, probably by burning a little earlier than your current Manoeuver Node. In your image, taking the current node as 12 o' clock, I'd bring the node back to nearer the 1 or 2 o' clock positions.

the orange line represents your trajectory immediately after the burn, out to the edge of the mun's SOI.  The purple is your orbit once you cross back into Kerbin's SOI.  It doesn't look like it makes much sense now, but as you approach the SOI change, the Kerbin orbital path will align with yours.  Remember that it will take a few hours for your ship to reach it, and in that time the Mun will move some distance.
