Deductions & credits

No the refund went up because it gave you the Stimulus amounts again on 1040 line 30.  You must have entered the amounts you already got wrong or in the wrong boxes.  Did you enter them in the 2 boxes?  

 

If you entered the total you got for both rounds in the same box it would think you didn't get the other one.  The IRS knows how much they already sent you.  You tried to claim it again on line 30.  Or did you get the second one after you filed?
