Do I mail out this Form 1040-V Payment Voucher? I amended my federal tax return and received a refund after corrections. I already paid the original tax bill I owed tho.

I filed my federal and state taxes already, but I received a notice from my employer of a corrected W-2. I amended both my federal and state returns, and received a refund on both of them.  TurboTax said to print out this Form 1040-V Payment Voucher, but I already paid my initial tax bill in full when I originally filed my tax returns. Do I just mail out this payment voucher by itself, with no form of payment for the IRS?
