I mistakenly order the home and business tax program off the american website. Order #qstca128994348 which is of no use to me in ontario. can I get it exchanged somehow?

You will need to contact the customer service team in the US at https://ttlc.intuit.com/ to get a refund, as we don’t have access to their billing system.

You can purchase Canadian versions of TurboTax on this website: https://turbotax.intuit.ca/tax-software/index.jsp
