Checking over my return I see a deduction for business expenses of $43. Can you tell me how turbo tax got this figure?

We cannot see your screen or your tax return, so no one can tell you what the $43 is for.   Are you self-employed?  Did you enter business expenses on a Schedule C?   Where exactly are you seeing the $43 that has you puzzled?

You need to go through your business entries to see where that number is coming from.  To go back to your business entries:

1. Open or continue your return
2. Navigate to the Schedule C section:
   • TurboTax Online/Mobile: Go to Schedule C.
   • TurboTax Desktop: Search for schedule c and select the Jump to link.
3. Answer Yes to Did you have any self-employment income or expenses?

Review your entries to see where that $43 is from.  Feel free to reach back if you have more questions and give us more details.
