OK State tax return not factoring in my 529 contributions as deductions. Return only has std ded and exemptions, but 529 contributions were higher. How do I correct?

Individual taxpayers may deduct up to $10,000 in Oklahoma 529 contributions each year from their Oklahoma adjusted gross income, and taxpayers filing jointly may deduct up to $20,000. Carry forward larger amounts up to five years.
