@raul_m , as an American citizen, where one lives , one files as a citizen i.e. form 1040 or 1040-SR. She cannot file as a Non-Resident or as a Resident Alien -- your accountant is wrong. Please follow TurboTax instructions -- she files a 1040-SR no matter where she lives ( permanently or otherwise ).
If you need more help on this please, let me what I can do for you or the help you need
