How in TurboTax would I report a "Long-term transaction not reported on Form 1099-B" for Form 8949? I need to report funds from a cash payout when my employer was bought

It's Option F on Form 8949. I had to calculate this amount, as it was not reported in any documents from my bank, broker, etc. It's capital gains from a cash component of the payment we received when my company was acquired. Thanks.
