If you think you can reset everything and replay the first game, that would probably be ideal.But assuming that you've placed at least 1 sticker and that you can't remove it, in this specific instance, I would recommend you take the loss and draw the next legacy card during the second epidemic of your second January game.
Reading the next legacy card now would also be fine, but it will ask you to make a selection according to an algorithm that's based on the current state of the board, so if you've already cleaned up your game it might work slightly better to resolve it during your second game rather than between games.
