When entering my turbotax deluxe license code, in a second accout, in order to download turbotax onto a second computer to file a second tax return, intuit's website tells me "This license code has already been associated with an account.  Please check that account and look for it in Downloads."  The product specifically was advertised as able to file 5 returns.  How can I download it?
