The doc for my amended fed return is the diff between what I paid minus the deductions in the amendment. Do I send this without any payment as this should be a refund?

Do I need to send the voucher in even if the amendment results in a refund?

Does the Amended  1040X return show a refund?  No do not send any vouchers  that print out.  The 1040V voucher is for what your original return would have been if you did not amend.  But have you paid the first original Tax Due?  Do not amend until your first return is fully processed and you paid the first tax due.

1040X has a line - Line 16 - for what you  paid with your original return.

If you didn't pay it, that line will be zero.

Print and review carefully your Form 1040X before sending it to the IRS.
