How can I do another return on my login?

[dallasonny]

My son is 30 and I want to do his taxes on Turbo Tax but use my login.

TurboTax Online is only good for one return. You would have to create a new account for your son, using the same email address but different username. Follow the steps below to create a new account. https://ttlc.intuit.com/replies/3288574

To file an additional return using TurboTax Online, you will need to create a new account.  Please see the following TurboTax FAQ for instructions on how to start another return using TurboTax Online.  If you have several returns to file, you may be interested in purchasing a TurboTax CD/Download, as you can  e-file up 5 federal returns for no extra charge, whereas you will be charged for each return (unless eligible for free filing) using TurboTax Online.
