My guess is you would be able to sell them in Schwab. If the shares are allowed to move over to Schwab from TD Ameritrade, you should certainly be able to sell them.
There may be a requirement to call in to Schwab, and have a broker sell the shares for you (hopefully they would waive the broker-assisted fee) Not sure, but if they are restricted in some way, Non-DTC eligible etc. I'm guessing that whatever process was allowed in TD Ameritrade, it will probably be the same with Schwab.
Or you could just hold on to the stocks once they're in Schwab. Hopefully, those three stocks (CNNA, ICOA, WALN) eventually explode upward and it makes all this pain in the ass worth it for you lol. Who knows.
So yeah, let them transfer over to Schwab, I think you should be good.
Good luck
