To decide if my 2023 state tax refund is taxable income for 2024, TT asks me to look at line 5 on my 2023 Schedule A, indicate whether the box on line 5a is checked (it is not), and enter the amount of 2023 state and local taxes I paid. Does this mean just the amount on line 5a (state and local income taxes) or the amount on line 5d (income + real estate + personal property taxes)? I'm guessing it's the latter.
