Filing Taxes in the US when you are abroad

Hi everyone!

I am so confused how to even approach filing taxes in the US while I'm living in germany. I have lived and wored here in munich for almost two years now, so I have not lived or worked in the US since August of Protected content . I have no investments, houses, etc. in the US and have a small bank account that is rarely used and has no deposits going into it. I feel like because of this, it should be pretty simple for me to file my taxes? But I can find no information on the correct forms or the right steps to take based on my situation.

I got a quote for Protected content to have someone help me...so I am really hoping someone here has done this before and can give me some cheaper advice! :)

Thanks a lot!
