Should I add my mom's Canadian address to complete this (haven't lived there in 5+ years)? It really won't let me fill in the review with a non-Canadian/US address

On the Contact Information page in TurboTax Online 2018, answer YES to the question “Is your mailing address outside Canada?” at the top of the page. Then, even though it will still say Province, Postal Code, etc…, it will now allow you to enter a foreign address.
