I had no problem with going to the "Other Oklahoma Credits" page and clicking "Update" under the Credit for Employees in the Aerospace Center. I then put in the dollar amount for "Credit Established During Current Tax Year" and "Unused Credit Carried Over from prior Year", no problem.
The Problem:
But the instructions say, "Be sure to include a copy of Form 564 with your return." So I downloaded and filled a pdf copy of Form 564. But WHERE should I attach Form 564? I don't see anywhere where I can attach pdfs.
