Backdoor Roth Help

Hi, 

I did backdoor Roth IRA conversion in 2024. 

I put $6500 in my traditional account but the money grew to $6503. 

I converted all to Roth IRA which is $3 more than max allowed. 

I understand I need to report $3 as a taxable event and report it but not sure how I can do it on Turbotax online. 

Also, it seems I may have not done it correctly in 2023 (same situation) based on how my form 8606 looks. 

I believe line 10 should show the extra amount which it doesn't. How do I correct it? 

I am referencing it to
