Advanced level - Backdoor ROTH IRA conversion timing

Hi all, I had a very specific situation on handling Backdoor IRA transition to Roth. I've found this option last minute and contributed 6k to my traditional IRA on April 17, one day before the 2022 tax submission deadline. The money was posted on my Fidelity account but not settled, so I could not convert to Roth IRA before the tax day. Am I still good to convert now, considering the funding happened on April 17 or it should have been funded and converted by April 18? Or shall I just leave it where it is in Traditional IRA to be safe?

 

I have also received a form 5498 about the 6k traditional IRA contribution from Fidelity. Will they change it to Roth if I am even able to convert?

 

My 2022 tax filing deadline was automatically extended to October, so I had a bit of time to figure this out. 

Thanks in advance.
