How did you receive the gifts from your father and brother? Were they cash gifts sent to you in the U.S. via wire transfers, money orders or checks? If so, you are correct that Schedule B should be checked "no" as long as you don't have any bank accounts overseas. If the money still sits in some overseas banks with you as the owner, then you may be required to not only check the box on Schedule B, but may also be required to file a Foreign Bank Account Report (FBAR), Form 114 electronically with FinCEN and IRS form 8938 with your Form 1040.
If your father's and brother's money were sitting in some U.S. bank accounts all along, there may be a gift tax filing requirement.
You complete Part IV to report the gifts from nonresident alien if the total amount exceeded $100,000.
I'm new to TT, the easiest way to find an input screen is probably go to Schedule B and right click on the box, that should take you to the screen for you to answer Yes, and the name of the country.
