I did not receive a 1099-B because a bank or brokerage was not involved in the sale of the stock. TT still asks me to upload my 1099-B for the IRS. What do I do?

I was given stock of a small C corp back in 2014. They repurchased the stock from me in 2019. I do not have a 1099-B because a bank or brokerage was not involved. When Turbo Tax says, "Now we'll help you upload your 1099-B since the IRS requires a copy", I have the choice to upload a form or skip? Is it acceptable to skip this step?

In the sales section when entering the specifics of the sale, I chose the option "Long term did not receive 1099-B form".
