Ok, i just transferred GTS to PS 5 and got everything in 22 minutes, my first two attempts didn't bring photos and videos and took hours.
Just make sure you are logged in to both consoles , don't need to be connected as long as there both on the same network.
Do the GTS save game data transfer only , mine was 280 MB, takes 30 secs.,then PS 5 will do a re-start, then go do the main game transfer, mine was 112GB, took 20 minutes.
Edit: When you start GTS there might be some added downloads that pop up and auto download and install(LHTT, etc) and when you go into your garage it takes about 20 minutes for all the car icons to show up.
