Here is the answer I found online
"Here's how you can tell which deduction you took on last year's federal tax return: If the amount on Line 12a of last year's Form 1040 ends with a number other than 0, you itemized. If this amount ends with 0, it's likely you took the Standard Deduction."
look at my tax return of 2021. And I know I took standard deduction that year. How shall I understand the above answer?
And For year of 2023, there is no 12a on 1040 form, so where can I find out the type of deduction? And I am very sure I took standard deduction for 2023.
Thanks
