1040-V and amended return reducing tax owed

E-filed in February and scheduled payment (wire transfer) for April.  Subsequently got a corrected 1099-DIV from my brokerage which reduced my tax burden by $450 or so.  E-filed the amended returns and was instructed to print out a 1040-V and mail it in along with payment (my original owed amount less $450).

 

Since I scheduled my original return to pay automatically via wire, do I need to mail in this payment voucher at all (and include a check)?  Thinking no but worried the amendment somehow canceled my wire transfer for my original return.

 

tl;dr - E-filed and set to auto pay via wire but amended and now owe less.  Do I need to do anything beyond filing the amended return?
