Should Iinclude my 1040 if I eFiled it but need to send a check for the payment with 1040-V payment voucher
Sorry for the last minute question, I already eFiled my 1040 earlier however, I need to pay due (I selected the send by mail option).
When I followed the instruction, it seems like I can only mail the check with the printed out Form 1040-V Payment Voucher. Am I correct? Or, do I need to attach a copy of the 1040 too (just for the payment)?
Many thanks in advance!
