Jacket help

Hello!
I need some help here.
When I turn the piece do I knit all the way down or just back to the marker again?
Thank you in advance!

TURNS:
Work shortened rows as follows:

  • Work row from bottom edge to neckline, turn piece and work return row. Work next row to Marker-1, turn piece and work return row. Work next row to marker-2, turn piece and work return row. Work next row to marker-3, turn piece and work return. Work next row on all sts, turn piece and work return row *. Repeat from -. There are now 10 rows towards bottom edge and 4 rows towards neckline.

KNITTING TIP:
Work the turns as follows: K tog the last 2 sts before marker, turn and work return row. On next row make 1 YO over the turn and work the YO into back of loop on return row.

Continue in garter st with turns until piece measures 25-27-29-32-35-38 cm / 9¾’’-10 5/8’’-11 3/8’’-12½’’-13¾’’-15’’ from casting on row – measured between marker-1 and marker-2.

You’ll knit to the marker, then turn and go back. If there’s no marker at that end, knit all the way to the end.
