Having to amend my 2023 tax return, to date I have not received this tax refund yet. After months of IRS extensions, and reviews, it came down to a simple error. I loaded an erroneous travel W2 from an incorrect year in the amount of $2500. This was not enough to change my overall tax bracket. It did change my refund amount of an estimated $7400 to $7200. However, when correcting the 1040X, it now says I have to pay $266. Why? Why am I having to pay this $266, when I haven't received my initial refund for that year? Why wouldn't the corrected amount just be sent when this amended return is finally sent to me?
