Last year I used 2017 turbotax software for tax return, but in recent days I just found that my 2017 state/federal tax returns were all rejected because of AGI/Pin mismatch.
Now I want to amend 2017 tax return and resend, but my laptop has been replaced long time ago (I don't have 2017 tax return locally). All I have is a tracking number that turbotax sent to me in email.
How can I find last year's tax return? or do I need to download 2017 software and fill up the forms once more? After that, can I send the return through software or should I mail it by myself?
