The result of your entries into the app is that the forms for the IRS have been created and submitted to them or at least ready to submit to them. When you finish the app, it allows for printing the output in several forms, one being pdf. I recommend printing the forms to a pdf, printing it out or at least look at it on the computer so that you can inspect the output. Perhaps you have last year's form to compare it to.
In any event, you should be able to figure out whether or not the W2 information resulted in appropriate output from the app.
