TurboTax does not send you tax forms. The TurboTax program is do-it-yourself software to assist in completing and filing your federal and state tax returns.
The TurboTax online editions are for completing one tax return per account and User ID. If you need to complete another tax return using the online editions you would need to create a new account with a new User ID - https://turbotax.intuit.com/personal-taxes/online/
You can have up to 5 User ID's associated with one email address.
