E-filed Federal and State returns have both been accepted. Do I still need to mail in form 8453 and 8949? I thought I already included this information in my filing.

I e-filed my taxes for 2018, and TurboTax is prompting me to print out form 8949 and 8453 to physically mail in as supplementary info.

But I already included these same documents in my e-filing by importing all of my brokerage activity. Are they really just requesting a physical copy? 

There are also 2 copies of form 8949 in my document list. One is a single page with just one transaction with code "M" in Col (f). The other is 109 pages of trading activity (I know, a lot. But I specifically chose desktop version because it was supposed to be able to handle it).

Do they only want the single page form with the unique code? Even so, I'm pretty sure that's already included in my filing, so I'd just be giving them something they already have.. It just doesn't make sense to me.

Ended up just mailing in a 1099-B for what appears to be a summary transaction on that one page copy.
