Paper check received after I claimed recovery rebate credit

My bank Suntrust was part of a merger last year and I was instructed by my bank to claim the recovery rebate credit for the second stimulus payment. I was told explicitly that I would not receive a paper check from the Treasury.

 

Last week I completed my taxes and e-filed with Turbotax. I claimed the second payment as recovery rebate credit as suggested.

 

Today, I unexpectedly received a paper check. Can I just destroy the check?

 

Thanks,
Sam
