I can't get my state refund until I fix an error in my TC-40W but it won't let me edit it.

To fix something on the state return after already filing the federal return, Sign In to your account and select the Fix my return button. Follow any instructions to update the information causing the rejection.

If you cannot open the return, select Add a State to get back in. Since the return was never accepted, it just needs to be re-submitted. Do not start an amended return.

Form TC-40W errors have resolved for some users by entering wth instead of WTH. Others went back and re-entered the W-2 or 1099 manually to accomplish this.

If the federal has not yet been accepted and approved, wait for that before re-filing the state. For more information, see: How do I e-file my state after I already filed my federal?
