The box 12 has a CODE  A  ??? Very unusual ... add that to the box 4 amount ... now is she over the max amount of $7,960.80?   Is that the mysterious excess $2111 ?    Or is the box 12 really a code AA (more common).   

 

Now look at your W-2 box 4 amount ... if you indicate it belonged to her and not you  ... if you add this amount to her box 4 amounts  is that the 2111?
