Please see the following information :
To enter a W-2 with an employer's address not in the United
States:
In the section on the TurboTax form W-2 for employer name
is a box labeled Address Type.
Click on the dropdown and
choose Foreign
Address .
You will be able to enter a City, Province, Postal Code and Country.
Here is also a post i found that might be helpful;
Easiest
was to click the "+ Add W-2" button which takes you to the "Here's your
W-2 info". Here you can now "Edit" the downloaded W-2. Select "Other"
for "Location" and then you can select "Foreign Address".For
both approaches above, in the "City" field enter "<city>,
<province>, <postal code>" as each appears on your paper W-2
form. For "Country" in the wizard, select the appropriate
country. "Canada" in my case. On the form, put the country code, "CN"
in my case, in the "Foreign Country" field.
