Nope. The alert warned folks that once you hit send it is on the bus and the bus wont' return until at least 2/12. You will just have to wait for that return to clear and then amend. This situation is exactly why I don't like preparing returns in January.
Prefect example of why you shouldnt send them in early.
Maybe you'll get lucky and IRS will reject it on 2/12, then you can fix it.
Otherwise you're stuck having to amend when that form is finally ready, Im guessing early March, or file a superseded return original return, but that can only be done on paper, so thats an even poorer option.
"because client found other w2 for 2020."
They are not even due to be provided until end of Jan; that means Next week people who can't remember where they worked should be getting the paperwork to remind them what a great 2020 they had.
