After you file

Before I new my refund was rejected by my bank, I went online on Where's My Refund and it said it was deposited with my bank on 2/28/2021.  However, when I called my bank to confirm it had been returned to the IRS, I discovered they returned it to the IRS on 2/19/2021.  However, Where's My Refund status hasn't changed.  Could that mean that they issued a paper check on 2/28 (which is a Sunday, by the way) and, if so, why haven't I received it.  That makes 9 business days and I still do not have it.  Last person at IRS told me it takes 6-8 weeks to get the paper check.
