1099-B

my 1099 B has neither an acquisition date nor a cost basis. From my records, the acquisition date was 3/19/2024., so I can enter that manually, but I still don't have a cost basis. The sold date was 4/2/2024. I called the company, and they don't have it. Turbotax will not let me finish without the cost basis.  I don't know what to do.
