Deductions & credits

I’m in Costa Rica.  I have no income in the States, but I do receive a very small amount of interest from my foreign account with over 10k in it.  TTax says i can not file electronically this year anyhow and I wont owe any payments since I don’t have income…right?

 

Do i really have to pay TTax for such a basic filing, especially if i have to do the FBAR on my own anyhow?  It is there a free method of doing this?
