@Englishbob let me add a few things:
After you unplug the power from the turntable, use blue painters tape to hold both the protractor and platter into place. You don't want anything moving around on you while you are trying to align the stylus. It'll make things far easier for you and leaves no residue when removed.
You can print an alignment protractor or get an inexpensive one from eBay. I'd recommend the MoFi Geo Disc though. It's $50- but a one time purchase. I've had mine 30 plus years and have used it countless times. It makes alignment super easy.
Set tracking force for 1.65 grams. Align after setting tracking force, not before.
Make sure your headshell is level left to right when looking from the front. You can get an inexpensive bubble level from Amazon. If it's off, there's a small screw on the underside of the headshell where it attaches to the arm tube. Loosen slightly and adjust the headshell until it's level. Snug the screw. Don't crank down on it.
This isn't nearly as difficult as it may seem. Take your time. Be patient. If you need me to walk you through it in real time, I can walk you through it by phone.
