I have no idea what form I used. I do know that I paper filed those years and it didn't cost me money, only time, a few evenings, reading IRS publications and googling 'expat taxes please help'.
The reason I ask is because for the forms I mentioned, it's very easy to either make an error or fail to file a form you were required to.
The fact that you mentioned "paper file" is a bit worrisome. You were required to file an FBAR if you had foreign accounts (such as bank accounts) totaling more than $10,000, and given your stated income, that seems likely. FBAR must generally be done electronically, and is a separate process from your tax return.
Normally, I found, when filling out a 1040 and walking through line by line, you are able to discover the forms you need and guide yourself quite easily. In the case of citizens living abroad, there is a publication as well that mentions everything, including all the forms and the FBAR you talk about. I found the process is quite discoverable and linear.
Also - the FBAR did not apply to me based on how I moved my money back to my domestic account, the foreign account was a current account for local bills, its balance never exceeded $5k.
