Help with 1040-V after I amended return, but never filled out a 1040-X?

  • Hello, after I filed with my W-2 Form and my returns got accepted, I received my 1099-INT in the mail. I then amended my 1099-INT and e-filed, which also did get accepted. 
  • My question is; do I have to mail my 1040-V Federal Taxes that I owe ($99)? Because I already made an arrangement to pay my Federal tax in March.
