TurboTax software indicated that I was required to file a non-resident return to Oklahoma. For tax years 2016-2019, my taxes were completed by a CPA and I owed state taxes each year. H&R Block software (completed online but not submitted) also shows a tax liability.
Reading through Oklahoma Form 511-NR documentation shows that $10,000 can be deducted from the unearned income when determining state tax bill.
