I'm not an accountant and I'm not familiar with Canadian tax laws but I've used 1099s a lot, for a variety of reasons. I'm pretty sure the 1099-INT is for interest income. Are you sure the 1099 you got from your US employer said 1099-INT rather than 1099-MISC ? The TurboTax software should walk you through additional sources of income. Also I could be totally wrong about all of this. As I said, I'm neither an accountant nor an internationally employed contractor. Good luck!
