How do I file multiple returns under one account? I'm using the TurboTax for sole proprietor.

You need to create a separate online account for each tax filer. You may use the same email address for up to 5 accounts. Note: It may be more economical for you to switch to the TurboTax CD/Download software product, which lets you e-file up to 5 federal returns at no additional cost.

The First TurboTax FAQ below provides instructions for creating a new account in TurboTax Online. The second FAQ has instructions for upgrading from TurboTax Online to TurboTax Software.

But it give me an "This license code has already been associated with an account. Pleas check that account and look for it in Downloads" error when I try to download it into a different computer with a different account. Any suggestion? Thanks.
