Why am I being asked to pay in for state taxes when I amended my original state return to unclaim any homestead credit?

I was originally getting $800 from state taxes but they were requiring me to send in a renters certificate for the homestead credit, which I didn’t mean to claim any. I amended my return and changed my homestead credit questions to where I wouldn’t be claiming anything and now it’s tellin me I owe in $600 even though I haven’t received anything from the original amount?
