Thank you. Do you know where I would fill it if I didn't receive any tax forms?

You're going to report it as Foreign Income and see if you qualify to exclude any of it for 2017.  To do that, follow the interview steps:  To report Foreign Earned Income and Exclusions:
1.  Click Federal on the left-hand side menu.
2.  Click Income across the top.
3.  Scroll down to Less Common Income and click Show more.
4.  Click Start or Revisit by Foreign Earned Income and Exclusion.
