Amended Return 2021 - Do I need to send in printed copies in mail?

I amended my return for 2021 using TurboTax yesterday. My original submission for both Federal and State was accepted. The reason for amendment was because I had forgotten to add 1099-B form and after adding that there were no refund related implications. 

 

After submitting the amendment, I have already received email confirmation that Federal Amended Return was accepted but TurboTax mentioned that I need to print out the Federal Copy and send it via physical mail. It also generated form with payment stub which was meant for the original amount that I owed.  My original submission already had bank account information to deduct the amount owed from my bank. 

 

My question is;

1. Do I need to print out and send a physical copy of all forms including amended 1040X? 

2. Do I need to send in payment for the amount owed along with this? 

 

Thank you for your help!
