Is form 3921 required for reporting ISOs?

I acquired "X" amount of stocks from a NQSOP (non qualified stock option plan) in 2021 and Disposed off "Y" stocks to cover for taxes. I have received 1099-B for the Y stocks disposed. How do I tell TurboTax that the Y stocks sold were to cover taxes for the gains on the NQSOP?
I was hoping I would receive 3921 from Fidelity but I did not.
