I had to go throw twice and fix my information because my taxes kept getting rejected for missing informations much for reviewing it before submitting/helping fix it
I have been using TurboTax for the past few years. They make it easy for you. Just upload a pic of your w2 and they basically do the rest. When you don't under something they always have a little question mark to click on that explains it very clearly. Why pay hundreds of dollars when you can do it yourself with TurboTax's help.
Turbotax is a very great site to file your taxes independently. It literally walk you step by step to do your taxes and help with tax breaks. It cant get no easier than this. I call this the one stop shop it is fast fun and friendly.
