I've had the same issue. I have tried to clear my browsing history, cleared my cache, and cleared my data. I deleted the W2 and even changed browsers. I even tried entering the data manually. The issue, as far as I can see, is that the state return appears to be partially filled out before even getting started on the federal return. When the W2 is entered - either manually or through upload - it doubles the state withholding.
This is driving me bonkers. Is there any fix?
