I don't do evergreens any more. But like RBG, I would counsel that, this late in the season I would not do much beyond learn how to use a chop-stick to test when watering.
I would also urge your tree live out of doors.
Late in your winter you should have completed purchace of appropriate soil for trees in pots. Um, and maybe dug out a pair of toe-nail clippers for your first nipper.
In general, bonsai are built from the stump up. Preserving your base, and determining which branch(s) to conserve as your new apex. Draw-draw-draw do pencil scetches of your tree as it is, and what you will keep after your first chop. And how you intend to wire that new leader, to its new position.
In order to make this tree come into proper proportion you will need to read what those proportions are, and how to bend your tree to its new stature.
First stylings profit from measure twice-cut once.
Styling "pads" as RBG shows in his examples are ten or more years away before doing them.
