Do I use my TurboTax username to do kids taxes?

Or do I make a username and password for them? Thanks!

Each tax return requires a different account which means a different user name and password. You can use the same email for different accounts.

For multiple tax returns, it is usually a better value to buy the CD/download product unless some of the returns can be done using the Free Edition. Up to 5 federal returns can be efiled using the CD/download product.
