Can I take a traditional IRA deduction for W-2 monies paid for vested RSUs in Retirement ?

Now in Retirement I have some income appearing on a W-2 from the company I retired from almost 2 years ago. The W-2 shows amount from finally vested Restricted Stock Units (RSUs) that were still in effect at time of Retirement. Both Fed and State taxes have been taken out. Shouldn't I be able to deposit some of this Post-Tax income into a Traditional IRA and take a 2024 Tax deduction to reduce my Tax Bill ?
