does turbotax 2025 deluxe consider the new $6000 social security deduction? my return was less than last year.

It is not a credit but a deduction.  It only reduces your income before the tax is calculated.

Nothing about Social Security has changed. It can still be taxable.  There is a new Enhanced Senior Deduction. This deduction is intended to provide tax relief for seniors and is in addition to the existing Standard Deduction or your Itemized Deductions.  Expires December 31, 2028.
 

It is automatic based on your age.  It is not part of your Standard Deduction and not connected to getting Social Security.  The new Senior Deduction (it's not a Credit)  is separate and in addition to the Standard Deduction or your Itemized Deductions on 1040 line 12e.   The 6,000/12,000 senior deduction will be calculated on 1040 Schedule 1-A page 2 Part V Enhanced Deduction for Seniors which goes to 1040 line 13b with any other Sch 1-A amounts.  Turbo Tax automatically includes it if you qualify.   If you are married you have to file a Joint return.

For Single the deduction starts to phase out at  75,000 and maxes out at 175,000
For Joint  the deductions starts to phase out at 150,000 and maxes out at 250,000
If you are married you have to file a Joint return
 

The up to $6,000 senior deduction has no effect on how the taxable portion of Social Security benefits is calculated 

As VolvoGirl said, TurboTax gives you the deduction for seniors automatically if you qualify for it. VolvoGirl told you where you can see it in your tax return.

Your tax return is the form you send to the IRS that shows your income and calculates your tax. The money that the IRS sends back to you is your refund.

Many things can affect the amount of your refund besides the deduction for seniors. Your refund being less than last year might have nothing to do with the deduction for seniors. Compare your 2024 and 2025 Form 1040 line by line to see where the significant differences are.

Oh I forgot to attach the 1040

Thank you all very much!
