How do I connect protax to be able to file my corporate tax return?

Hi bookings-flowtim,

Welcome to Community!  It's great to hear that you'd like to file your corporate tax return with Pro Tax.  This is available in QuickBooks Online Accountant.  However, if you've added an accountant to your books, you can exchange files with them seamlessly, so they can create and submit your returns for you.  Please don't hesitate to reach out to QuickBooks Online Accountant Pro Tax and Workpapers support, for more invormation.  

If you have any other questions, please feel free to reach back out.  We'd be glad to help!
