If you used the Desktop program you first need to update your return with the filing status so it knows it was filed and accepted. Open your return and go u p to menu item
File>electronic Filing>Check Electronic Filing Status
Then save your return and close and reopen it.
But I have seen posts from people saying they can't efile the amended return from the Desktop program. Seems to be a glitch. It might have been reported.
But if the withholding was wrong the IRS should catch that and fix it for you. You might not need to amend. Have you got the first refund? Did the W2c increase or decrease the withholding?
