How to claim prorated Enhanced Senior Deduction

I am a single filer, over 65 years old. My 2025 income is between $75,000 and $175,000.  According to IRS, I should receive a prorated Enhanced Senior Deduction (phase out begins at $75,000 and deduction is eliminated at $175,000).  The prorated deduction does not appear on my 1040SR and my forms does not include Schedule 1-A.  Has anyone seen this issue of not receiving the prorated deduction?
