After you file

So after the 800 offset did you get $300?  1,100 - 800 = 300.  The $1,800 Stimulus was included in the $1,100.  Sorry you already got credit for it.  You can't get it again now.

 

 It was used to reduce your tax.  You must have had a 700 tax owed on your income.   Then getting the $1,800 for the Stimulus gave you an 1,100 Refund.  Then they offset 800.  Sorry you can't get more.  The math works out.
