If you purchase one of the CD/Download versions, you may complete 5 e-filings and
will receive one free state filing for the one time cost of the
product (when using the Basic version, one free state is not included).
If you purchase the online version, you will not be able to use your Turbo Tax to create another return. You will have to start a new account with a new
unique user ID for another tax return. The online editions are only
good for
completing one tax return per account and user ID. See the FAQ below to create a new account to prepare the other return:
