Laid down after Botox, now uneven smile. Is there something that can be done or should I give it more time? It's been 12 months.

Your symptoms are most likely due to something else, not due to the Botox. You should see your general physician for an evaluation and work up.  Botox does not last more than 3 to 4 months and it does not typically affect the cheek when injected into the crow's feet area. 

That would be very unusual, since Botox always wears off within three months.
Generally, if Botox causes any unwanted effect, increasing the movement of the involved muscles will help the Botox wear off faster.  
Your treatment site would then revert to your baseline without permanent sequela.
