Itemized deduction question

Attempting to do my mother in law’s taxes. She is in an assisted living facility with the chronically ill designation. Her 2024 income is 35k and her deductions amount to 124k. She did not pay any federal taxes on her income. When I input everything into my turbo tax software it tells me I have the deduction credit and not the standard deduction. It does not show she will be receiving a refund. Is this correct??
