I need to start another tax return for a different person

[kenneth9420]

I used TurboTax online to file my 2016 returns and need to prepare my mothers return.  I don't see an option to start a new return when I login

Only one return can be prepared on each account when using the online product. You must create a new account and pay again (unless using the free edition) to prepare another return. The CD is a better bargain for preparing multiple returns.
