A homestead exemption is not a property tax credit and typically does not require you to amend your return. Before I can say for certain, what State do you reside?
Many states offer homestead credits to residents who meet certain criteria. The homestead credit is based on the assessed value of your home, the amount of your property tax, and your income. This is not a refund of taxes it is a credit you receive as a homeowner if you meet the criteria.
