Required to send Form 1040-V after e-filing amended return?

I paid ~$22,000 in taxes when I filed in April.  Now, I filed an amended return after receiving additional Form 1065 Schedule K-1s.  This resulted in a refund of ~$3,000.  Upon completing the amended return, TurboTax instructed me to mail a From 1040-V that shows an "amount of payment" of ~$19,000.  As I've already paid the $22,000, I will not be paying the $19,000 as stated on the Form 1040-V.  Must I send the Form 1040-V anyway?  Doesn't make sense.
