Looking for the rule on when you consider that you've sold the "replacement stock" from a wash sale.
We have quarterly purchases of employer's stock. A sale in April, 2020 (of stock purchased in Q1/2019) at a loss became a wash sale since there was a 3/31/2020 quarterly purchase. For the very next sale (in May 2020), do I consider that I'm selling the (now) oldest shares (acquired Q2/2019) OR do I consider that I'm selling the replacement stock purchased 3/31/2020? (FIFO has been used. For this question, assume equal # shares bought/sold each time.) I understand we'd use the original Q1/2019 purchase date for the holding period of the replacement stock, but can't find any info on how to sequence the sales when you're using FIFO. The math on the broker's 1099 B supplemental presentation appears to consider the replacement stock (bought 3/31/2020) to be the next batch sold. Any reference info would be most appreciated, too.....
