When checking upon where's my refund there is no update
Only the IRS knows what all they are doing with your return. What is the current message/status you see at the IRS "Where's My Refund" tool?
https://www.irs.gov/wheres-my-refund
How long has it been since you filed? Did you efile, or did you file by printing and mailing?
