You do not enter a federal refund anywhere. It is not taxable and doesn’t apply to the next year. You only enter state refunds if they are taxable on your federal return.
A State/local Tax Refund is taxable if you itemized deductions on that prior year's federal return and took a deduction for state income taxes instead of the sale tax. You got a deduction benefit for it so now you have to include it as income. If you took the standard deduction it is not taxable and you don't need to report it.
