State tax filing

So I just received a notice from Oregon that denied my Subtraction Code 327 which was Deferred Compensation I received in 2024 from deferred salary and bonuses (Washington employer, I moved to Oregon in 2023) that were deferred between 2009 and 2012, but payments did not start until 2021 and will be paid over 5 years.  I elected to take the payments per the plan over a 5 year period, but they were delayed to start payments until 5 years after I left the company.  I left in 2016, payments started in 2021 and will completed in 2025.  Again I earned the original income in Washington, left that company in 2016 and moved to Oregon in 2023.  If I am reading your post correctly, the deferred compensation payments are over a 5 year period (the actual payments), and I treated them as not taxable in Oregon.  Washington has no state tax, so I did not pay state tax in Washington, but my understanding is that this would be an eligible Subtraction from Oregon taxable income.  Am I looking at this correctly?
