I entered my date of non-residency incorrectly, and now it only shows up correctly on the worksheets, but not in the final page. Where do I edit this?

You can enter or edit your dates of residency on the My Info page. Click Edit to the right of your name, and scroll to #2. You enter the state of residence as of the last day of the year. Answer YES to I live in another state in 2019. A second dropdown will appear where you can enter the additional state and the date below it.
