Verify that the enhanced senior deduction factored in correctly onto your original 1040 filing - see Line 13b.
Is the enhanced senior deduction flowing onto Line 4b of the 2025 1040-X in columns A, B, and C? Or is the issue you're seeing isolated to one of the columns: A, B, C? Can you share some of the numbers you're seeing vs. what you'd expect to see for Line 3 minus Line 4b = Line 5?
We'll need specifics to determine if the issue is with the calculation of 1040-X, or if it is elsewhere in your tax return input. If there's a software issue, you may need to send a token of your tax return file so it can be escalated for investigation.

What should I know before amending my return?
Here are some things to know before you begin:
- Make sure you really need to amend.
- Wait until your return has been accepted (or mailed if paper-filing).
- Use the same TurboTax account you used to file your original return.
- Once you begin your amendment, you'll see your original return. Only make changes to the areas of your return that need amending. The refund calculator will start new at $0 and only reflect the changes in the refund or tax due.
- Any changes you make to amend your federal return will automatically be transferred over to your state return.
Melinda - to answer you questions,:
1. I have $12,000 in 1040-X line 4b in columns A & C which was correctly transferred from my 1040-SR line 13b.
2. The numbers I am getting in 1040 X as an example:
line 1- A = 140,852
2-A = 34,700
3-A = 106,152
4a-A = 357
4b-A = 12,000
5 = 105,795 (= 106,152 - 357, should be 106,152 - 357- 12,000 = 93,795)
