Print and Mail 1099-B?

Do I need to send in a paper copy of my 1099-B to the IRS?

 

I have never seen this before, and it is only asking for one of my 4 brokerage accounts.

 

Is asking me to mail it because it does not automatically link to TT and I entered the summary manually? (unlike the other accounts)

 

It is all "covered" therefore already submitted by the Broker. My 1099 is over 500 pages! Thanks
