As a dual citizen, you are required to show your passport if citizenship for the receiving country - I have dual citizenship and it feels weird to show one passport to get on a plane and another to get off, but it’s what a customs officer will ask of you when you arrive.
Since OP was never an American resident or paid taxes, he or she shouldn’t need to file taxes or be flagged on a system for anything anyway.
