TurboTax does not get any information about your return or refund once it has been accepted., only the IRS would know when you will receive your refund.  At this time the IRS is not processing mailed in forms or returns.  They stated once they re-open they will start processing mailed in forms & returns.

All you can do now is keep checking the IRS website, Where's My Refund, the website updates once a day.
