Fedral Refund

Hi All, 

I have a questions about my fedral refund (For 2022) which dropped for about 5k compared to year 2021, I compared total income of 2021 vs 2022 there is only about 2k increase in it, in 2022, and I have same numbers of kids as 2021 but I am wondering why the refund dropped this much. Can someone please tell me the possible reasons/situations of this drope in refund and if there is any way to fix that. I haven't file my taxes yet so I will be able to chnage that. I am using desktop version of TurboTax Delux.

 

Thanks for the Help.
