I e-filed an amendment to my 2020 taxes. I owe additional taxes. Will the additional amount be deducted from my checking acct like original amount or do I mail a check?

Amended returns can't be e-filed, you must mail them in. 

If you are paying additional taxes owed with your amended tax return or Form 1040X, you will include a check or money order with your amended return when you file it.  

An amended return has to be printed and mailed in order to be filed, per the IRS regulations. Three weeks after you have mailed your amended return you can track it by visiting the following link: Where is my Amended Return or by calling the toll-free telephone number 866-464-2050.

Turbo Tax must have updated this option for this year because it did allow me to amend online and efile the updated tax return.  I have received the following message from the IRS "Your amended federal tax return was accepted by the IRS."  I guess I'll wait and see if both the original amount owed and additional amount owed from amended form are deducted on 4/15.  If not, I'll submit the second amount by mail by May deadline.
