I just had a client who had all zero's in column B & C.  (of course column B will always have a value )  Client called the marketplace and the "professional" he talked with said " the 1095A is correct." I convinced him to call back and talk with a different "professional".  He got the numbers over the phone.  Of course issuing a correct 1095A was too much trouble.  12 years and the marketplace is still a joke.
