Thanks for the instructions but this question is actually concerning transfer/transactions between crypto exchanges/wallets. If there is no such external transfer, reporting 1099-MISC and 1099-B from single exchanges should work with TurboTax as usual. The concern is to report through a separate crypto gain/loss aggregator such as TaxBit/Koinly that combine transactions across ALL the different exchanges/wallets/DeFi to track and conclude the right cost basis for gains/losses. In that case, reporting 1099-MISC and 1099-B from one or more of the exchanges seem redundant and may not capture the actual cost basis. That is why the original reply by @KrisD15 suggested to report as a subtraction entry. I am just not sure if it is appropriate to deal with 1099-B as well in the same or similar way.
