Tax Mapping - Missing from Workpapers and Income Tax

I would like to customize GIFI tax line mapping for export into Pro Tax for a T2 in Quickbooks Accountant.  The tax info kind of imported into ProTax, but some of it is missing, which seems to imply that some sort of GIFI file was created. All of the explainers tell you to click the tab in Workspace, but it just isn’t there? There is a tax line function in the income tax tab, but it’s coming up empty too. 

What am I missing? Is this a subscription issue?
