How do I transfer my info from last year's return? (Online version)
TurboTax Online will automatically pull your past year tax information if you are using the same account this year as last year. You can also transfer from a .tax file saved on your computer.
On the first page after signing in you will see Transfer last year's TurboTax return from your computer. Once you've entered information into TurboTax, the ability to transfer is no longer available.
