After you file

It has been 4 weeks since the IRS received my 2020 Tax Forms via Turbo Tax and I have not received my refund.  It did include the second stimulus payment of $600.  I received my 2019 refund in two weeks.  I am concerned about the delay.  How do we get a straight answer on the status of our refunds? I just get the message that it is being processed and a date will be provided when available.
