This is great information.
In this case, ALTABA, shares were sold and money got reinvested in BABA shares. It was a taxable conversion. Also - not all of my shares were converted. This created the confusion. I have both a 1099-B total gain and a separate cash TENDER amount seen on the ETrade tax form. It looks like the 1099-B gain is the sum of the TENDER and the cash that was reinvested so I don't need to do anything else about the cash. Your reply helped clear that up. Thank you.
