Expat: How do I account for my RSUs sold to "withhold to cover" I do not have a W-2 and all my income and shares vested while living abroad.

How do I account for my RSUs that were taken out by Morgan Stanley for taxes "withhold to cover"?  I do not have a W-2 and all my income and shares vested while living abroad.  I also do not see these reflected in any forms (1099s) given by Morgan Stanley.  Thank you.
