@hiro0910 if you indeed entered the US with F-1 visa in 2016 and this was your first entry to the USA, then yes, your exempt period ( five years ) would have expired on 12/31/2010. And if you continued to stay in the USA, sometime during 2021 you would have become a Resident for Tax purposes. Thus you needed to file 2021 return on form 1040 , which TurboTax supports.
W-9 is for the use of persons with SSN and because you have filed a 2021 return I am assuming that you have a tax id ( SSN or ITIN). Thus when you open a bank account or any other action that requires the "other party" to report your earnings etc. they should ask for your tax ID by having you fill out a form W-9 NOT W-8 BEN. The latter is generally used to request tax-id from Non-Resident Aliens either in the USA ( without tax id ) or abroad but have financial interests in the USA.
Does this answer you questions ? What are you trying to do ? Is this job related or investment related ?
Is there more I can do for you ?
