How to file form 1042-S code 29?

I am a resident alien for tax purposes but last year I opened a couple of bank accounts with my passport and I received two forms 1042-S with code 29 (one for each account). I already filed my return so I have two questions. 1. Should I file an amendment? 2. If so, do I need to include the information of my 1042-S as another form?
