I was hammering in a drywall anchor where my stud detector said there was not a stud, but it turned out to be wrong! This put a clean break in the stud up and down. I cut into the drywall at the spot and a good distance below it to confirm the split was going down quite a bit. I drilled on the left and right of the split and was going to screw on a metal brace. Would this be enough? Should I put in several braces, or do I need to remove the drywall and completely replace the stud?

I'd say none of the above.
You're looking at 2 individual pieces of lumber, you didn't split anything.
Even if you had split it I would lose zero sleep over the situation. Framing has redundancy built in. That entire stud could be removed and you would likely have zero structural issues.
Kudos for being cognizant about your actions. There are some thoroughly dense people in this world that remove entire load-bearing walls without a second thought so the structure sags throughout the decades.
You're fine, patch the drywall and continue with your project.
If you had truly damaged the stud to a point it was structurally compromised then at most I would cut away enough drywall to sister another stud next to it. Removing the damaged stud would inevitably cause huge problems for whatever material is on the backside of the stud.

I have considerably high doubts that a plastic wall anchor could ever split a healthy stud. If it could then it's not a healthy stud and I would pray that the rest are not equally weak.
Kevin HI I see what the others have seen even if the stud was split which its not you would not have to replace that stud because it can still hold the load. If you need a fastener in the area where the old hole is you could put another wood screw just a 1/4"to the either side of it if you need a fastener to hold new the new drywall repair on but that stud is fine. There is no reason to do it but if you needed to close that gap you could easily use 4 2-1/2" inch wood screws to pull the gap back together. Or squeeze some bondo into the gap with a shim just to hold a new screw. Thats way to much work that stud is sound. Just put new fasteners beside that gap. With plaster over it it will be invisible and safe. Cheers!
