Were you already signed up from previous years; i.e, were you an Advantage customer prior to the 2016 tax season? If you are a new Advantage customer and you signed up after the 2016 deadline in early November, then you signed up for next year's 2017 product, not the current 2016 product.
If so, you should have a download at this link:
If the download file isn't there, then look to see if you have multiple accounts (User IDs), and if the download might be in another account. To get a list of your User IDs and recover account access, you can use the tool at the link below. If you have more than 1 email address, you should run the tool on each one. Once you know all of your User IDs, then try each one at the download link I provided above.
NOTE: Before running the account recovery tool below, log out of all Intuit accounts including this user forum, or you might end up in a loop. Then clear your browser Internet cache, close your browser, then reopen it, and go to the link below. You may wish to copy this link so you can paste it into the new browser session.
If still no luck after running that on each email address you have, then run the tool yet again, but this time choose the small blue link that says "Try something else", and it will look you up by SSN and other parameters.
If you still can't get your download, then here's how to phone Customer Support during business hours. Use the form at this link to be assigned a phone number. The number will not display when they are closed.
