An RMD is not a single transaction. It is simply the least amount you must withdraw to avoid a penalty, you can always withdraw more if you want.
As long as you withdrew at least as much as your RMD amount before 12/31/23, you are completely fine.
Turbotax only asks if your withdrawal was an RMD because there are certain things you can't do until you make your RMD, such as you can't do a rollover to an IRA until you take your RMD first. There is no where on your tax return to check "this 1099 is an RMD" but "this other 1099 is more than my RMD".
Enter the first 1099-R, when Turbotax asks if this was part of your RMD, say yes, it all was. Then enter the second 1099-R. When Turbotax asks if this was part your RMD, say yes part of it was. turbotax will ask for the amount.
Again, this has no effect on the tax or penalties you owe, as long as the total you withdrew over the year is more than the minimum amount you were required to withdraw.
