I have the Premier version of Turbo Tax. How many Federal and State Returns can I submit? My daughter needs/wants to use my Turbo Tax.

With TurboTax Premier (CD/Download), you can e-file up to 5 federal returns with up to 3 state returns each.

You can prepare as many returns as you like, but after the 5 first returns, you have to print and mail them.

Please see this TurboTax Help article.
