How do I get a refund for the online Turbotax? I've always purchased the cd but thought I would try the online this year. Bad idea. I need to do 5 returns.

I want to switch to purchasing the CD/Download but I've already paid for the online version. I'm not paying full price. Where does it say "online only covers one return"? In all the years I've used TurboTax I've never had to pay for the program more than once. It isn't like the online version is less expensive. Is there a way to convert what I've paid to buy the CD/Download so that I can do my children's tax returns?
