Had exercised ISO stock 3 times since it was granted in 2013 spread across 4 years.In 2016 the company was acquired and we cashed out. However a portion of it was in escrow to be given to employees in 2 installments. We got first installment in 2016. Form 1099B have 2 entries. 4500 stocks cashed out on 1/2016 and the escrow payment of 4500 stock on 8/2016. Here we only had exercised 4500 stocks in total, so not sure how to deal with this.
Btw the rest of the ISO stocks in 1/2016 was converted to the acquiring company stocks.
