With the CD/download software---desktop software----you get up to five federal e-files and e-files of the states attached to them. The five federal e-file limit is an IRS limit---not a TurboTax limit. If you have more than five federal returns to file, you have to file the additional ones by mail.
Please note--when you use the CD/download you get the free federal e-files and the state program to prepare state returns. There is an extra state e-file fee for each state return that you e-file. That fee is $20 and increases to $25 on March 1. You can avoid the state e-file fee if you file the state by mail.
If you purchased the TurboTax Deluxe desktop CD/Download edition, the software provides 5 free federal e-files (number set by the IRS). After the 5 e-files have been used all other tax returns have to be printed and mailed. You cannot purchase any further e-files.
If you purchased the software from TurboTax or a retailer who had the Deluxe edition for Federal + State, you will received one Free state software download.
There is a state e-file charge that is currently $20 (increase to $25 on 03/01). This charge can be avoided by printing and mailing the state tax return.
