If you didn't pick a specific date, it will default to April 18, 2017. If you did select a date, that information is printed on the filing instructions page that can be found in download all forms and worksheets. It is in the balance due/refund section. Another way of getting "back into" your tax return and review the information you put would click ADD State. This is found under some things you can do area on your tax timeline. You do not actually add a state. The software will open your return and you can click on the File tab to review your payment options. ***Remember you wouldn't file again*** The IRS already has your tax return. Do not make changes, just view what information you submitted.
You can always contact your state about your inquiry. This TurboTax FAQ has a link you can click to get their information.https://ttlc.intuit.com/replies/3302452
