Are you having problems paying for your return or are you trying to NETFILE your return?
I am having struggles paying for the Turbotax service- even though I tried clearing my browser, new device, different banks, and all... still being declined, and getting no help through the phone as I am in Hungary so the quality is super poor- meaning I'm unable to file until its resolved.
You will need to input a Canadian address on the return. When you print it, you can manually change the address to your address. You will need to print and mail your income tax return. Unfortunately, you will not be able to NETFILE.
Thank you for choosing TurboTax.
