Sorry, no. All the online versions of Turbotax only prepare the current tax season.
I recommend downloading the IRS forms and instructions and preparing the returns by hand. If your children's income is only from working, and all they are doing is filing to claim a refund of their tax withholding, their returns should be very simple. Less complicated than high school math class and also a good civics lesson. You would just need the 1040 and instructions.

You can similarly download your state tax forms from your state tax web site.
If using Turbotax downloaded to your computer, the cheapest version available is Deluxe at $80, but one copy installed on your computer can prepare more than one return.
