Hello, I was NOT able to find the QSBS exclusion option if I selected "Incentive stock option plan (ISO)" under "Choose the type of investment you sold". I was able to find the QSBS exclusion option if I selected "Stocks (except stocks acquired via employee stock plan)" as described in the recommended answer here.
What is the reason for the difference? Is stock acquired via an ISO not eligible for QSBS?
