How can I estimate my tax refund for 2023-2024 or estimate how much I will have to pay, if I do have to pay?

Try the Taxcaster tool:

@xmasbaby0 unfortunately Turbo Tax Taxcaster is only for 2022 and will overestiate what is owed (because the tax tables were adjusted for inflation) 

this calculator will provide a 2023 estimate
