Found an Error
I recently e-filed Fed and State. I have since noticed an error, which I have corrected. Neither return has been accepted yet. Can I un-submit, then resubmit, or do I need to wait until the FED accepts the return, then submit an Amended return? (FYI: The error: I claimed the $1500 Child Tax Credit under my name, rather than $750 for me and $750 for my spouse - Married - Joint Return).
