Filed 2017 federal taxes online Turbotax with a withdrawal from checking in April. Overlooked one fed tax deducted. Need to file amended return. How to do it and when??

[Rachel_W · Accepted solution]

If your Tax Return has already been e-filed and accepted by the IRS, you will need to wait until it has been fully processed and your payment has cleared.  In your case, you will need to wait until your payment is withdrawn from your checking account in April.  Since your return has already been accepted, there is no way to cancel or change the payment.  If you were to send your Amendment in before your payment is processed, it would cause confusion with the IRS and delay your refund.

Once your payment has been processed, you can Amend your return and add your overlooked deduction.  You have 3 years from the due date of the return to file an Amendment.
