How to report a qualified small business exclusion post-sale distribution

I do not know how to account for a capital gain exclusion and need some help. In 2019, a start-up medical device company was purchased by a larger company. I was an investor in the smaller company and made four stock purchases over time, so I received a payout that qualified as a small business stock gain exclusion for two of the purchases because of the length of time I owned the stock. With TurboTax’s help, I was able to take care of my filing.

An additional part of the deal included post-sale extra payouts if the acquiring company met certain sales thresholds for the first year, which they did. This year, I cannot find a way to report my distribution in TurboTax, as it is not a sale. My friends have said that it is not taxable. I manually completed Form 8949, but will that be forwarded when I efile? Can you help me?
