Please help with entering a nondeductible traditional IRA and recharacterization to Roth IRA with the following dates

Contribution for tax year 2024 made on April 10, 2025.

Filed extension for tax year 2024 on 04/15/2025

I am over the income threshold for both Regular and Roth IRA deductible

Recharacterized traditional IRA to Roth IRA.  on 09/30/205 for the contribution that was made on 04/10/2025 for tax year 2024.

 

I have tried multiple suggestions and spoke with TurboTax but I keep getting multiple conflicting answers.  I tried entering and selected recharacterization but it applies a 6% penalty on my $8000 nondeductible contribution.  Please note I do not have a 1099-R because all of this happened in 2025.  I expect Vanguard to issue one next year for 2025.  

 

I need the steps how to enter this correctly so I do not get audited and show what I did is allowed.  Thank you in advance for your help.
