USA Form 3520

[lvmehta]

I filed form 3520 last year since I received inheritance from non US citizen and non US resident and it was more than 100K. While filing I checked box for "initial" because it was my first time.

There is no activity this year to file form 3520 and there will not be any activity in the future. Do I need to file anyways to check the box "final"? If yes do I have to write my inheritance I received last year again or keep all sections empty?

Thanks
