You keep posting that as though it somehow buttresses your assertion - it does not. The closest it comes is here: “In his first inaugural address Lincoln declared that he had “no objection” to the Corwin Amendment, nor that it be made forever unamendable.”

Having no objection is not the same as “pushing a constitutional amendment”. Not today, not in 1861.

Having "no objection to it being made express and irrevocable" from the President and leader of your party is a means of reassuring his party that they would suffer no penalty for voting in favor of this thing.

How many Republicans voted for that monstrosity? I'll bet you it was the vast majority of them.
