If you have a high volume of trades, your 8949 will be consolidated onto one line with a description "see attached statement".

This is in accordance with exception 2 of the IRS 8949 instructions, and it is how they prefer high volume traders to report (rather than sending in dozens of pages of 8949's).

This is not something that is wrong with your report.

You should include the csv attachment with your consolidated 8949 when filing.
