I am an expat. Filled my 2016 with my accountant in US, now want to to use turbotax for 2017 is it easy to continue with some business losses from US to carry over?

Yes  it is easy to enter business losses carried over.  If you're referring to Schedule C losses, you can't choose to claim them in a different year. Normally, a business loss reduces your other taxable income in the year that it occurred, and there is no carryover. 

 

For other business losses, just use the Search tool at the top right of the TurboTax screen.
