Hi,
I have filed my 2020 tax return using TurboTax a few days ago, but I just realized that, as NonResident Alien, I should have used form1040NR, rather than form 1040 that I actually filed from TurboTax.
From previous posts, I've basically seen how to file an amended federal return. I just have two questions about that:
1. Given my situation, when should I file my amended return for the current year? Can I just file the amended return right now, or should I wait until either IRS processed my refund, or notice me for an amendment?
2. What if it turns out that my amended return using 1040NR results in less refund, while the IRS processed my refund based on my original wrong form 1040? How should I return the extra refund? Is it supposed to be filed together with the amended return, or some separate filing after I get reply from IRS about my amendment?
Thanks a lot!
