Question - Filed an Amendment Electronically with TurboTax Desktop version

I forgot a 1099-B when I filed my federal return but caught it pretty soon thereafter. I have already received my refund. I went into TurboTax (Desktop edition) and went through the process of filing an amendment and adding my missing 1099-B. TurboTax gave me the option to file electronically which I did, and the government already accepted it. TurboTax also gave me the option to have the funds deducted from my bank account on file to pay the tax back to the government for the missing 1099-B.

 

TurboTax software gave conflicting messages. When I finished filing the amendment it said to mail in form 8453 and it filled it out for me with the last box checked. That form says to "FILE THIS FORM ONLY IF YOU ARE ATTACHING ONE OR MORE OF THE FOLLOWING FORMS OR SUPPORTING DOCUMENTS." The last box that is checked identifies the attachment required in my situation, which is Form 8949. However, that check box for form 8949 attachment also indicates that the attachment of Form 8949 alongside form 8453 is only necessary .."if you elect not to report your transactions electronically on Form 8949."

 

My question is this, does TurboTax software submit these forms electronically when I filed the amendment electronically via the software? In other words do I still need to mail in Form 8453 and attach form 8949, or was that all done electronically? Initially I thought I needed to mail it but then I figured it must have done it electronically or it wouldn't have been "accepted" by the IRS and marked complete. I'm assuming at this point they'll deduct the amount from my bank account on file as I selected, and I don't need to mail these in manually.

 

Can anyone help me answer this for certain.
