IRS:
Schedule A is missing from your return. Complete the form with information that supports $46,700 on line 12e.
Response:
I calculated the Standard deduction of $46,700.00 on line 12e of Form 1040SR using the Standard deduction (Married filing jointly with 2 boxes checked) of $34,700 from page 4 of form 1040SR plus $12,000 new additional deduction for Seniors per the IRS FS-2025-03 titled "One, Big, Beautiful Bill Act: Tax deductions for working Americans and seniors"
I should have entered $34,700 on line 12e and $12,000 on line 13b.
I have attached Schedule 1-A.
