If i owed in taxes when i originally filed, but now i get a refund after amending them, will i get the refund amount plus the amount i overpaid from my original filing?

If i owed $500 in taxes when i originally filed, but now it says i am to recieve $500 after amending it, does that mean i will recieve a total of $1000 ($500 for the return and $500 for the amount i already overpaid)?
