Your description of the way you did things is confusing. First of all, a state refund is not a "deduction" on any tax return. When you receive a state refund it is entered as INCOME for the federal tax return for the tax year in which you received the refund IF you itemized deductions for the earlier tax year. Otherwise you do not even enter the state refund on your federal return.
Since you say you did not file your 2019 state return until 2021 it would have been impossible for you to receive that 2019 state refund before 2021. And....we do not know if you even filed your 2020 or 2021 tax returns since you have not mentioned if you filed them.
Explain more clearly what you did with those tax returns.
