Get your taxes done using TurboTax

Thanks but I'm an orphan.  My mom died last year.  I'm thinking I can buy the downloadable version from Amazon because they accept my credit card and paypal.  Then it's prepaid.  I'm wondering since the taxes are completed if Turbotax will pull the information in and if this method of making payment has any issued?  You help is appreciated very much.  I had my taxes done on time, it's simple because I'm retired and they owe me a refund so it seem odd that the one thing holding everything up is paying for the service.  Who'd have thought Turbo Tax doesn't want my money.
