I have the same problem. cost basis looks zero and federal income tax withheld looks zero even though I paid those taxes in my paycheck.
the problem is that these RSUs were vested in 2016 and I sold them last year. I do not have paychecks anywhere for 2016. What can I do? Paychecks only archived for last 3 years online and there is no way for me to find 2016 paychecks and see how much tax I paid for that RSU. What can I do?
