W2 Box 1 Wages reflects 401k contributions, but not $5,250 in HSA pre-tax payroll deductions. Box 12 Code W shows HSA contributions $1,500 Employer and $5,520 Employee.

I'm trying to figure out why the 401k pre-tax deductions are reflected in Box 1 Wages, but HSA pre-tax payroll employee contributions are not being removed.  Implies I'll be taxed incorrectly on my HSA contributions.
