If a 2020 tax return was already e-filed and the UCE was duplicated, should we amend the return ?

Yes.

Just be sure it was in fact duplicated on in the transmission that was filed.

this is true, that update changed previously filed returns if you didnt lock them prior to installing the UI update.

That is why it is a good idea to PRINT and SAVE the actual return e-filed .... Just my opinion
