TP has a code W  on W2  with $1000 in Box 12.   It is not included on his Taxable wages since the entire $1000 is from employer. 

It ends up being taxable on 1040 line 8 coming from Form 8889  line 9/11.

Dont see anywhere on form 8889 to decrease the $1000 so that it will not be taxable .

If there is a cell,  it has to be overidden.  

Thoughts?
