How to use Form 8453 to transmit paper copies of 1099-B transactions

[edithers]

I have checked the box on Schedule D indicating I am mailing in copies of the 1099-B transactions with

Form 8453, and on the Form 1099-B worksheet I have filled in the type of transaction boxes (A for short

term and D for long term) and the total gross proceeds and total cost basis for each type and filled in the description box 

(brokerage account).  Why do I have an error indicating I must fill in the date sold boxes (clearly 

impossible unless I enter each individual transaction, which is what I am attempting to avoid)?  How do I

fix this?

Avoid the mail in issue and attach a PDF file to the return.  Scan the documents and on the E-file Menu item attach it as Form 8949 Attachment.  In the body of the Sch D form use 12/31/20 as the sale date and Various as the purchase date for each A-F category.
