You do not need a 1099-B. You need the details of each sale that would be on a 1099-B if you got one, because you have to enter those details in your tax return, on Form 8949. You need the purchase and sale dates, the purchase price, the sale price, and the amount of any disallowed loss from a wash sale. If you can get those details by importing the information, that is completely acceptable.
CORRECTION: I believe that for 2022 the wash sale rules do not apply to crypto.
