Schedule A is available now. Unless you have a disaster loss then it will be available on 01/17/2024.
Although, your post shows you are using the TurboTax Free online edition which does not support Schedule A for itemized deductions. You would need to be using the Deluxe or Premium online edition for the Schedule A and those editions are not Free.
Additionally you would need total itemized deductions which are greater than the Standard Deduction for your Filing Status to have any tax benefits.
