Should I amend our filing for 2025, married filing jointly with total B income of $245956.00? I think we would qualify for the $12000.00 credit.

Can you clarify?  What is total B income?  Schedule B for interest and dividends?  What do you need to add to amend your return?  

And you should  have automatically received the $12,000 Senior Deduction.  Check your return line 13b.

[VolvoGirl]

Is that your AGI  $245,956?  That is almost the max of 250,000.  You  would only get $485.

the senior item is not a credit but a deduction computed on Schedule 1-A, Part V, that carries to line 13b of your 1040. It starts phasing out with modified adjusted gross income above $150,000 for a joint return and is completely phased out with MAGI of $250,000 or more. Not sure what you mean by B income. MAGI is used, which is calculated in Part I  

TurboTax calculates it automatically based on your ages and MAGI.
