If I amended my 2020 return through e-file and it's been accepted, do I need to mail the 1040-X form in? Additionally, when I filed my amendment I put in my information to pay the amount due, but it has not shown up in my bank account, and in the instructions, it said to mail in a check, or pay using Direct Pay. So I paid with Direct Pay. Was this the wrong thing to do? Will my account get charged twice?
