Hi Kyle,
Your G03 line looks okay, though for doing a 90° arc it would be easier to use R2.0 instead of K-2.0, not that it is wrong.
The issue is the line before "G01 X28.0" as the X works in diameter on a lathe, so to produce a 2mm radius you move 2mm in Z but 4mm in X, so you would need to start at X26.0.
