Hi Tom, thanks very much for your answer. By end of 2018, I have no share left in my account. But just purchased a few back in January of 2019. Then sold them all again on the same day. I have no share in my account since then. In this case, am I able to claim the "wash sale loss disallowed"next year? Something really confused me is that my real net loss was a little more than $5k, but the 1099B states I have wash sale loss disallowed of more than $40k...
