OASDI is the SS tax.
No, if the SS tax is the only thing that has changed on the W-2C (box 4), then the IRS says you don't have to Amend your 2020 taxes after you receive it.
IF they change something else too, then it depends on what that change is, and you'd have to ask at that time whether an amended tax return is needed or not. e.g. Certain types of new information showing in box 12 of box 14 would not require amending.
