2023 instructions states line 12 of the 1040 form, "if I checked 4 boxes in the Standard Deductions" the table below indicates the Standard Deduction should be $33,700.

If all 4 boxes were checked then you are both age 65 or older and you both are legally blind.  Is that correct?

 

If you both are NOT blind but are age 65 or older then your Standard Deduction for tax year 2023 is $30,700.

Are you filing a joint return?   Are both spouses 65 or older?   

Is one or both of you also legally blind?

 

2023 STANDARD DEDUCTION AMOUNTS

 

SINGLE $13,850  (65 or older/legally blind + $1850)

 

MARRIED FILING SEPARATELY $12,850  (65 or older/legally blind + $1500)

 

MARRIED FILING JOINTLY $27,700  (65+/legally blind) )  + $1500 per spouse

 

HEAD OF HOUSEHOLD  $20,800 (65 or older/blind)  + $1850)

No, you state "both age 65 or older and you both are legally blind" but the instructions states: "both age 65 or older or you both are legally blind."

You are absolutely wrong, learn to read.
