After you file

While I was filling out taxes I missed box one on a W-2 and at the end it said could not file electronically because box one was empty so I went back and I filled it in but it still won’t let me file electronically do I start all over


You should not need to clear the return and start over.  Just delete the W-2 and then enter the W-2 manually, do not import.
