Smart check ask about schedule A 2023, but I have no schedule A last year

[Zc99]

In smart check, it says "State Tax Refund Worksheet: Item B must be entered. ". In Forms, I found it refer to 2023 Schedule A Line 5a. I didn't have a Schedule A last year (did tax filing through a CPA last year). It says if none then enter zero. But the description of it just refer to State and Local Tax. I can probably find or calculate this number from the state tax form last year. Should I enter zero or try to find out the actual number?
