Pattern help (socks)

Hi!
I’m knitting some baby socks,
This is my first time using dpk’s and working in the round.

I have completed the leg, on three needles,
6 stitches on the first and second needle, and 12 on the last,
now the instructions are:

Heel Flap
Set up row (wrong side): Turn work so wrong side is facing you, p12
For this section work back and forth on just these 12 stitches
Row1 (RS) Slip 1 purlwise, k1, repeat from to end of stitches
Row 2 (WS) Slip 1 purlwise, purl to end of stitches.

I’m all kinds of confused :sweat_smile: but mostly my question is,
How do I turn the work so the wrong side is facing me, when the work is on three needles?

Turn as you would at the end of a row. This video shows it:

You just work on the 12 stitches and leave the others alone until your done with the heel part then continue the pattern.
