Hi. On the white fields you left it's needed to complete it with fake details such as fake tracking code, fake address, billing and modify the botton bar code? First time I going to try this method motivated by your thread, thanks!

The bar code needs to stay untouched (I edited it for the post only) and the tracking number needs to be removed and/or changed.
UPS/Fedex/or whatever needs to actually scan it so it's in their system and reflects with the place you are doing this simple method with.

I have heard if UPS scans the label it reflects the actual return address in their system and if the person scanning it notices a totally different address it may be flagged for fraud manually, I don't know how true this is so I just keep the return address blank and change/remove the rest of the details.

You want no identifiable information returned to make sure the worker receiving the return is not able to link the FTID to your order, this is equivalent to simple boxing but does work.
