<prompt> Human: So I tried turbo tax vs. hr block, and the two refund amounts they let me file where incredibly different! So yesterday, I tried turbotax and it started off with a refund of 4,400 with one child dependent and then when I actually filed it, it dropped down to 1,000 stating the my 10,921 W-2 wasnt taxable or something. Since, it explained it, I went ahead and e-filed it, now I wish I didnt.Then I try the same thing with HR block after my co-worker told me about EIC I should be getting too, and according to their site it let me file for a 4,400 Federal refund PLUS a 374 refund!!!And now, it looks since I already filed the first one, I cannot re-file with the second?I saw you can do an amend form, is it much more complicated or not?Thanks! Sorry for the hastiness of this post, at work  <response>: You entered something wrong in one or both of the sites. TurboTax will figure out your EIC, if eligible. What is your AGI and filing status?
