Thank you so much if someone help me to find out my answer.

 Client sent me a form 8949 for crypto transactions which Coin Tracker recently extracts from some Crypto websites without any info from connected reporters. Everything is on form 8949, cost, proceeds, date....

Is necessary to fill out all boxes top of 1099-B worksheet, such as NAME OF REPORTER, ACCOUNT NUMBER and REPORTER TAX ID?

If yes, how can I find them?
