You could try 3 things.
(1) add the box 12 code W amount on another W2 for the same person.
(2) enter $1.00 wages on the zero wages W2.
(3) In the medical deduction section, HSA/MSA contributions, you can answer 'Yes' to the question, "Did your employer tell you about any other contributions," then on the following page put this in the box titled: Employer and payroll contributions not reported Box 12 of your W-2." Then, omit the actual W2 entry.
I recommend (3) first.
