Are sales tax and estimated taxes the same thing for someone who is self employed? Received letter from the state and they didn't include the taxes I paid in 2024.

I just received an adjusted refund letter from the state. They are claiming I never paid the quarterly taxes I paid throughout 2024 and this is causing my refund to be substantionally lower than what it originally was supposed to be. I have the receipts for all of the taxes paid each quarter, should I appeal? - Thank you in advance for any help!
