Each ONLINE account can only prepare one return for one person. Additional returns require separate accounts, and will be charged separate fees, unless you qualify for a simple free tax return.
The DESKTOP program that is installed on your own computer from a CD or downloadable installer can prepare an unlimited number of returns, with the first 5 eligible for e-filing. (The license agreement says you can use it for personal use -- i.e. family -- but you can't charge people to prepare thier taxes using this version.) (Or any version, actually.)
