Could you be more specific? No one here can see your return. What is your W-2 question?
Hint: Employers have until January 31 to mail your W-2s; it can take two weeks (possibly longer) for them to arrive in the mail. You should always wait for your W-2s and important 1099s (especially 1099-NEC) before filing (unless it's April 15, of course -- actually the 18th this year thanks to DC Emancipation Day).
To get to the section you need to be in order to enter the W-2, you will have to sign in, continue your return and in the search bar, type in W-2. There will be a jump to link. From there you can enter your W-2 information any one of the following ways:
If using your are using the mobile app, you can also take a picture of your W-2.
@ZoltanB45 The PM I received indicated they were being asked to enter a 2020 W-2 instead of 2021, which should NOT be happening in TurboTax Online. I replied to that PM with possible scenarios; they have not responded.
@Carry12201960 If it's asking about a 2020 W2 then one transferred over from 2020 and it wants you to fill it in for 2021. If you don't have it again this year or entered it as a new W2 then you need to delete the one that transferred over.
