Federal Tax Exemption

Hello,

 

I am the legal caregiver for my sibling. I am employed through the State of Illinois as such. In our recent meeting, they stated that if we are the caregiver for a relative, we are exempt  from federal taxes for the position. We are to enter this on or tax return.  I was unaware of this and have not claimed the exemption. 

 

A few questions,

 

1. Is this true?

2. If it is true, are there any requirements?

3. What would the procedure be to amend my taxes? Do I do it, or can I have TurboTax complete it for me?

3. How many years back can be amended? 

 

Thank you!
