If you want to file the 1040A you are able to do so by going to Turbotax.com and click on the blue button that says Start for free, once you do that it will give you a break down of which versions we offer and the prices next to each version. You will select the light blue one that says Free Editon. (below Free Edition it says Start for free) so you will click on that. It will start asking you questions. You will enter in all of your information and based on that information it will tell you if you qualify to continue to file that way. If at any time it asks you to upgrade or purchase another version then that means you do not qualify to file on the 1040A and you will need to upgrade. Not many people qualify for these free editions because they are short simple forms but if you are able to do so we encourage you to file this way.
Please let us know if you have anymore questions, we're happy to help you.
