Uneven smile and uneven neck. Was injected Botox 20 u around lips and DAO by board certified plastic surgeon? (photo)

This is unfortunate. You have two options. One, just wait for a couple months and the effect will wear off (it may happen sooner). Or, get a little more Botox injected into the stronger side to create more symmetry. Considering how high the one side of your lower lip is, I'd personally just let it wear off.

This will resolve.  Unfortunately it will take 3 or 4 months total.  This is unfortunate but can happen if the Botox is injected into adjacent muscles or diffuses into those areas.

Wow, 20 units is a lot for around the mouth and DAO muscles! Your unfortunate complication is likely a combination of too much Botox and poor injection technique. At this point I would not do anything else and let the Botox wear off. Things will go completely back to normal, but it may take 2-4 months. Sorry about your experience.
