A distribution reported with codes 4 and D in box 7 is ineligible for rollover. It would seem that either the ROLLOVER notation is coming from the entry of some other Form 1099-R or you have mistakenly omitted the code D as the second code when entering this Form 1099-R.
I suggest deleting this 1099-R form from TurboTax and seeing if the ROLLOVER notation disappears, then reentering this Form 1099-R manually, making sure that you indicate that box 7 has more than one code and indicating that the second code is code D.
