If I use sales tax as a deduction for 2020 can I deduct state income tax paid in 2021?

I have a feeling the answer will be NO but here is the question:

I didn't pay any state income tax on retirement money I got in 2020. I guess I could use the sales tax option as a deduction for 2020 BUT if I do this, will I also be able to deduct the 2020 state income tax I am going to have to pay from my federal 2021 returns? If NO, then I should not use the sales tax option in 2020 ?
