Get your taxes done using TurboTax

Thanks for the response.  I am inquiring as I do my own and my two sons taxes.  I've done theirs online and in the end it seems to cost more to file than using the deluxe desktop version I buy for myself.  I want to see what's legally allowed by using any desktop version to electronically file 3 federal and 3 state for 3 different individual filings at the most economical cost.
