"However, every other software system and CPA is preparing the form as part of the F1120S."

I am unaware of ANY CPA preparing the form as part of the 1120S.  Further, I have NEVER received this form as part of a 1120S K-1 given to me by a client, whether that K-1 was prepared with an Intuit product or not..  It is the client's responsibility to provide me the information necessary to prepare this form to attach to Form 1040.
