Thanks for your reply.

Yes, Proconnect is requiring the attachment of 7203 for a basis calculation as a shareholder for an S-Corp.  

If I reference another form other then 98 = Form 7203, it will throw a critical error: Form 7203, S Corporation Shareholder Stock and Debt Basis Limitations, must be attached as a PDF for electronic filing purposes.

Is this a glitch in the system, therefore making me have to mail in the return?
