Nondeductible Contribution

I asked this subject before and still not totally understood. I hope someone will get me on.

I worked for the government sector before and had a 457 retirement account and a Roth IRA Account. The 457 was a pre-tax contribution and Roth is not. In 2020 I retired and I moved my 457 to an IRA Account with Charles Schwab. I started to get my RMD from my IRA account a year prior and 2023 was my 2nd RMD. All my IRA contribution were pretax.

Now Turbo tax ask: Any Nondeductible contribution ?

I guess I didn't make any after-tax contribution to my IRA account even I did put my after-tax contribution to ROTH IRA,

the answer should be no, is that correct?

Thanks.
