After you file

@Dbanks558 have you checked the WMR tool and your transcript?

the IRS reported on Monday that they have completed processing of all tax returns submitted through March, 2022 that were error free.  That means you return must have contained an error

 

Is the $2800 you reference an exact number?  that sounds like two stimulus payments of $1400 each. Did you file joint? 

 

a few questions

 

1) did you receive the 3rd stimulus payment of $1400 per person in early 2021?

2) is there $2800 on line 30 for Form 1040?

 

if you answer 'yes' to both questions, that is the issue.  Line 30 should have been zero, meaning your refund is overstated by $2800 and that is why you haven't received anything.  check the two links above as I suspect you'll be able to see what occured.
