So you changed longstay visa not started. And you admit you already transferred 65k per month for at least 1 year. Thanks for confirming all i mentioned.
You can not use the 65k transfee method to start with. After the first full year its possible but you have to show a full year of monthly transfers at that moment.
You probably show it to the immigration officer. Later maybe to a customs officer if you have goods to declare or they pick you out for customs checks. Customs is about goods. Immigration is about persons.
