How do I enter my cost basis for an ISO granted and exercised before a company went public?

[reticulating]

I have ISO (incentive stock options) that were granted in 2010, exercised in 2012, and the company went public in 2018, and I sold in 2019.

I was able to enter an exercise price, exercise date, and grant date alongside the number of shares, the sold date, and sold price.

But I don't see anywhere that asks about my cost basis (how much I paid when I exercised in 2012 before the company went public and I was able to eventually sell).

your cost or other basis is your exercise price in 2012 and that's your Date Acquired

So the cost basis I paid in 2010 doesn't need to be explicitly entered anywhere?
