Getting Taxes Done in Tainan

I am trying to get ahead of the curve here regarding filing my taxes this winter/spring. Here is my situation:

Employed in the US Jan-Jul 2017
Working with ARC in Taiwan since Sept 2017

So I believe I will have to file a US and Taiwan return.

Typically I have filed using Turbo Tax. My questions are, has anyone used this software to file while living in Taiwan?

And in case this is not an option, can anyone recommend an affordable tax preparation service (preferably one that is easily accessible from Tainan and has English-speaking staff)?

Any advice pertaining to filing would be much appreciated.
