@recce36f4 , while generally agree with the comments / questions from my colleagues @rjs and @SusanY1 , I think we need more info from you for a definitive answer:
(a) need to know whether one or both of you are US person ( Citizen / Green Card ) and are you planning to file together ( Married Filing Joint);
(b) wife has a business -- does this mean that that is her total world income or does she also have some US active and/or passive income; How about your US and/or foreign income;
(c) is this your first filing with foreign income; when did you establish your foreign tax home;
(d) if you are also employed in Australia ( or foreign wages ) are you employed by a local entity or a branch or US govt.
Please note that while W-2 ( if any ) info is entered under wages in TurboTax personal income tab, foreign earnings i.e. Foreign Earned Income eligible for exclusion must be entered under the proper heading --- personal income --> next select " I will choose what I work on "; from the resulting drop down list , near the bottom under " uncommon incomes" select " Foreign Earned Income and Exclusion" and go through the interview process. You will fill out the form 2555 which checks whether you qualify for exclusion ( must meet physical presence test ).
Please answer the questions I posed and I will circle back and help.
