Held stock in partnership for three months, then converted to regular corp, box 20- Z shows "0" TT won't accept

My wife bought this stock in a partnership. After three months of ownership, it converted into a "regular" corporation.

 

The K-1 form has codes "V" and "Z" with respective values of "-1" and "0".

 

TurboTax will not accept the ")" without further information, supposedly on a "Statement A" that should have been included with the K-1.

 

There was no Statement A.

 

Not sure what to do here.

 

Can I disregard the code Z?
