Can I trust taxaudit.com? If so I will try to contact them. Unfortunately, Turbotax call center is not helpful for international calls. Btw, I moved out of US in 2019 to Türkiye. Most likely that is the reason why I didn't receive any other notice. I would appreciate any other potential source of help.
A little bit more detail: The brokerage firm sent a 1099B to IRS of my exercised, company issued stock options as if I haven't reported it. Eventhough it was part of my W2 and the taxes were paid, now IRS is asking for full taxes on the exercised stock options based on that 1099B. I will appeal and need a professional to take care of it as I am outside the US.
Thanks for the help
