I had the exact same problem you did, I finally got the federal corrected and ran its check, but when I ran the check on the state, the federal amount changed to the wrong amount. So I went back into the federal and corrected it the same way again, but this time I did not run its check again. Then I finished the state. (Someone on this blog wrong these instructions a short while ago.) Before I will send it, I manually checked the federal and it's fine. I have not checked our state's, yet - will do so in the next few days. (TurboTax had a similiar problem last year and didn't fix it. I can do a return by hand much faster than spending hours on various TT errors every year. I understand taxes.) A thing I thought of doing, is to fix and check the federal and send & save it separately. Then do the state, check, save & send it. Good luck...
