I sold stock options for a net of $2500. I had them withhold 1100 in taxes so I netted 1400. My 1099B is not showing taxes withheld yet they were. What to do?

Your best bet will be to get an amended 1099-B.

If the money was withheld the IRS will know it, because it will show up on your account for 2019, just like your withholding.

are these employer stick options.  or puts or calls on say AT&T

if employer stock ll the taxes withheld should be on your w-2.
