Retirement tax questions

That helps a bunch! And there's no limit to how much I convert that old money from the T-IRA to the Roth, correct? I just can't contribute more for 2024 since I hit that limit. 

 

Now hypothetically speaking, what if the $12400 from the T-IRA takes a loss and goes down to $11500 and then I convert it to the a Roth?
