TurboTax won’t allow you to input anything other
than a Canadian address. Please choose YES to answer the question “Is your
mailing address outside Canada?”. Then you will not have to type in your
address into the program. Since you have an address outside of Canada, you will
have to print out and file your return by postal mail. You can write your
address on the printout.
Also, be aware that TurboTax Online will only
accept a Canadian or US credit card in the payment area. If you don’t have a
Canadian or US credit card, you can try purchasing a prepayment code from one
of our retail partners.

If you have an iOS device, you can download our
iOS app and use that to pay for your return with ApplePay.
