Is there a way to find previous FBAR submissions? I do not remember if I filed FBAR last year, so can I still submit? Any inputs on what reason should I give? Thanks!

If I remember correctly , if you go to www.fincen.gov, you can find your submissions -- I tried it a few years ago.  If all you are trying for is to make sure you have filed for a year,  perhaps it would easier to file another for that year ( making sure it  represents actuality ) -- extra filings do not cause any harm -- better to be sure
