Get your taxes done using TurboTax

If you sold shares in 2021, you should not be reporting those investment sales in 2020. The income associated with the value of those shares  when they vested should be reported on your W-2 form. All you need to do is enter your W-2 form in TurboTax to account for that income.

 

So, you should report the 100 shares sold in October of 2020 and the cost of those shares, which will be the same or close to the sale price, since the purchase amount is what was reported for them on your W-2 form. The income from the vesting is reported through your W-2 entry.
