Cash App sent 1099-B and only shows proceeds, no cost basis. I only used cash app as a payment processor/collection service. Does this need to go under 1099B or Misc income section?

I used cash app as a payment processor and collected Bitcoin for various areas/transactions/services.  Cash App sent a 1099-B, but since I only utilized Cash App as a payment processor to receive the Bitcoin payments, how do I determine the cost basis.  Would this not be better placed on MISC income section or should I just use the costs basis of $0?

Thanks
