Pro rata rule for Roth IRA conversion, please help, Thanks!

I made an After Tax Traditional IRA contribution of $6500 for 2023 and invested it. However, I gained interest, so the Traditional IRA totaled to $6501 before I was able to convert $6500 to Roth IRA. Now I have $1 left in my After Tax Traditional IRA. Does the Pro rata rule for for Roth conversion rule now apply? How do I deal with the $1 left in my Traditional IRA on the Form 8606 for Tax Year 2023? Can I still roll the $1 to my Roth to bypass the Pro rata rule? But it’ll be over $6500 for Roth IRA conversion. What should I do? Thanks!
