I see. If I pay 1040x no.1 voucher, will my refund be processed after? 1040x no 2 voucher does not include the amount I paid from 1040.
1040 - pay $X -> I paid $X via TurboTax
1040x.1 - pay $X+Y (voucher only says pay $Y) -> I have not paid $Y yet
1040x.2 - refund $Z (voucher says pay $X+Y) -> I have not paid $Y yet
