For my Missouri State taxes, I opted to pay it directly from my bank account. I was sent "2022 Individual Income Tax Payment Voucher" to send with a check and I don't know why. Do I have to send this voucher with a check, or will it take the state tax payment out of my bank? If I do have to send in the voucher, does that mean I will be charged twice?
