I used the tool and it says that nothing has changed, but I am just wondering whether reporting the 1099-B from the stock options when they get vested need to be reported when I have already paid taxes for them, which is why overall nothing changed in terms of owing or getting a refund.
"You need to report a tax form you forgot about or received post-filing (most commonly a W-2, 1099, or 1095-A)." It says most commonly a 1099, so I am not sure if a 1099-B form counts or if it would have already been accounted for through my W-2.
