I am a Canadian with an H3 visa working in the US. I have worked in the US for all of 2018 (my only income is from the US). Will turbotax software work for me?

Yes, for your U.S. Tax return. Just make sure you use the U.S. version for your U.S. tax return.

Yes, it will.  As an H-visa holder, you are considered as a resident for tax purposes and required to report worldwide income including the US source.
