If I call the automated tax line or access "Where's my Refund" to check the status of a refund on an amended return, do I enter the total amount of my original refund, or only the amended amount?
You cannot check the status of a refund for an amended return on the automated tax line or by accessing "Where's my Refund." Amended/corrected returns are processed as quickly as possible. However, it may take 8 to 12 weeks or longer to process the return. If 8 weeks have elapsed and you have not received your refund, call (800) 829-1040.
