Get your taxes done using TurboTax

@pkI actually have a different issue now; I was about to post it in the "after you file" section but figured it would be easier if I just reply here.

I actually already filed my tax return without entering my foreign income because I thought I only counted as a resident since August, not for the whole calendar year (this was before I asked about it here). The tax return has been approved and I'm waiting for the refund to arrive.

I went through the TurboTax software again, this time including my foreign income, and the software tells me that I'm able to deduct all of my foreign income. My federal and state refund amounts did not change.

So my question now is, do I still need to file an amended return? If so, when do I do it? And how do I do it using the software? (I am using TurboTax Home and Business)
