@sweetsrw , while agreeing with @Kat & @Rick19744 as far as the question asked, I wonder are you US citizen / Resident ( Green Card ) . If that is true then yes you have to file a US return and the question regarding QBI is valid. Even then the question about your tax home would be pertinent -- if your tax home is Mexico ( i.e. you satisfy having an abode in Mexico, and pass the Physical Presence Test ) then your income , even if paid in the USA may be taxed by Mexico and also be eligible for foreign earned income exclusion. Every thing depends on facts and circumstances in this case. So please tell us more of the situation , including if this is your first year abroad and if your "employer" is withholding any taxes for you .
