I bought private shares of a start-up through a marketplace (EquityZen) in 2018 that matches investors with employees of start-ups and groups the investors in a Fund Series LLC specific to that start-up. I received a K-1 (1065) each year. Then eventually that company went public in 2021 and I received my shares in my brokerage account and sold them a few months later. On my 2021 (Final) K-1, Box 19, it shows a distribution amount in $$ with a code C next to it to reflect non-cash distribution; however, further in the TT questionnaire, it asks a number of questions about the partnership disposal to eventually calculate a long-term capital gain. And then separately, I have the 1099-B reported sale from my brokerage when I actually sold the (now publicly traded) stock. Where should I be entering the actual sale - K-1 or 1099-B? How to I adjust to avoid duplicate capital gains?
