VA 502ADJ

I have amended my 502 because of the ERTC receipt. Everything seemed to transfer from the federal 1120S to the state 502 form. There is also a necessary 502ADJ form but no information transferred to that form. Wondering if it is because there is no refund or taxes due with this form for an S corp? Or should something be entered because of the changes on 1120S due to ERTC?  Just seems odd to require a totally blank form.
