After Bulk Fermenation, the First Rise, you are ready to SHAPE the dough.

I liked how this step is explained in this video: Make Beautiful Sourdough with Claire Saffitz. I also followed tips from Modern Eats Farmhouse Easy Sourdough Bread Recipe. Click through to get the whole recipe and lots of good info.
Scrape the dough out of the bowl onto a floured work surface. Split in half two make two loaves.
PRE-SHAPE the dough by folding each side into the middle.
Let REST under a towel for 15 minutes.
Flour your proofing bowl(s) with rice flour.
Let the FOLDING commence.
FOLD the LEFT side over the CENTER.
FOLD the RIGHT side over the CENTER.
Grab the end and ROLL it up to the TOP.
PULL the dough towards you to create tension on the surface and form a round shape.
PROOF
Place the dough into the proofing basket with the SEAM SIDE UP.
Cover with a towel, and let sit on the counter for 1 1/2 hours.
When you can press your finger into the dough and have it slowly spring back, it's ready to proof in the fridge.
There are a lot of options of what to use to cover the dough, or whether to even cover it at all. Some choices I've seen are a towel, Saran Wrap, a shower cap, or a plastic bag.

Then you cover it and put it in the fridge. I've seen times ranging from 1 to 40 hours. It probably depends on how anxious you are. Experience will inform my future decision on this.
