Hi, I have a situation w.r.to stock sale. Specifically I acquired a stock in a startup in  jan 2019. The company got acquired in march 2019. Some of the proceeds were held in escrow account and given in dec 2020. Now I got 1099 for year 2020 with date sold as march 2019. I have 2 questions. 

1] when I do capital gain/loss Form 8949 for 2020 tax year, should the date acquired be jan 2019 and date sold be march 2019 even though I got funds in dec 2020. 

2] w.r.to [1], will it be long term or short term. 

Thanks
