Changing Copper Olive on TRV

It could be tape or anything white, but if hemp had been used, the joint would not have leaked. Tape is all too easily 'squeezed' out from a joint where hemp is not.
Always clean all mating surfaces of a joint before rejointing. Not to do so could compound your issue.
If you've got it to that point why not replace the olive? Worst case is it's a junior hacksaw and saw 4/5th through the olive and then a plain screwdriver in and twist to snap it off and replace with new copper olive.
That pipe certainly indicates that the removed ring was really graunched on, so put a thin smear of jointing compound on the pipe before you add the new ring and then a little after to ensure a water tight joint and then tighten into the TRV.
Others will disagree, but in that situation, I would fit new olive, gently tighten nut in order to compress olive, then wrap 3-4 wraps of PTFE around new olive and refit valve.
New olive.
Paste.

Whatever it takes.
It won't take a lot.
