I worked in ZNGA many years ago during which time I received both RSU and ESPPs (stocks were acquired in 2017-2018). The ZNGA stocks got converted to TTWO last year during a merger; and I see a 1099-B in my Etrade account. I am kind of lost on how to report all these "gains". I see 7 entries for RSU sales and one ESPP sale and one cash sale. Only one of the RSU sales have an adjusted cost basis, while all others are blank. What should I do here for the cost basis? Can someone also suggest what other things I might need to pay attention to here? Thank you.
