Retirement tax questions

Thanks for your response. 

So in my case, Since my $7000 contribution is not-deductible for 2024. I will file it in 8608 this year. 

For my next year filing, Since I will be converting that non-deductible IRA contribution of 2024 to Roth in 2025, do i still need to pay tax on my 1099-R amount ?

How should I enter 1099-R in 2025 return to avoid paying tax again on my non-deductible investment ? Will 2024's 8608 will help me to avoid paying tax on that 1099-R in 2025 ?
