I found that I bought the wrong version in Costco, then I bought the right on on line, can I get refund?
You can request a refund for a copy of TurboTax Desktop (CD/Download product) at the link below.
https://support.turbotax.intuit.com/forms/refund-request.jsp
The refund form is missing at that link
Wait a minute. You bought the wrong software at COSTCO? Take it back and see if you can get a refund from COSTCO--that is who got paid for it. Why would TurboTax give you a refund for something you paid Costco for?
