How do I calculate my Cost Basis on the ESPP stocks? Or even the adjusted cost basis? I've read that I can be double taxed if I don't do "something" I just don't know what that something is! I have the 1099-B and I've emailed Morgan Stanley because someone said I should have a Form 3922, but I don't. So if you can say on form xx use 1d minus 1a type of thing so I know exactly what to calculate and where to put it in Turbo Tax I would really appreciate it!
