Please, where i should put: -rescan ?
According to your previous posts, seems that you are using MAC.
For running bitcoin core with a startup option in MAC, you need to do the following.
[Ref.]Open the Mac terminal. Then type
open Bitcoin-Qt.app --args <options>
where <options> are your startup options. Just make sure to have a space between each option. Press enter and Bitcoin Core will start with those options.
Replace
option with
rescan in the code above.
