TurboTax calculates my taxes incorrectly the second year in a row

Last year 2024 TurboTax made me to overpay federal taxes. IRS returned me as a result of the program mistake $5,258.00. This year it looks like the taxes it calculates is too high. I entered the same data in ChatGPT, and it gives me the number of ~$3000 less. I'm vey upset and do not know what to do.  I bought the TurboTax Home & Business at Costco. What should I do? Who should I call?
