After you file

Thank you so much for your response. The answer to all your questions is no. We actually were entitled to a refund approximately 3K  what we received was the 3K minus the exact amount we paid each quarter( 4 times) for 2023 .

   We did not intend to make estimated  taxes for 2024   

We’re OK with them applying the 1600 to 2024 but we have no proof that that is what happened.
