How can I change 1095 a to 1095 c

You must have answered that you had health coverage through the marketplace.  Go to the Health section and change that.

every time i go into my return it doesn't ask me the question about my health care it skips that section and has assumed that i have 1095a when i actually have 1095c

To remove a 1095-A from your return:

1. Click Deductions and Credits
2. Scroll down to Medical and Click Show More
3. Click Start or Revisit next to the ACA
4. If you see a 1095-A in there, be sure to delete it. 
5. Select Continue twice.
6. Click Revisit next to the ACA and this time select No, I didn't receive Form 1095-A

This will remove any forms related to marketplace insurance and the premium tax credit from your return. You are not eligible for these if your health insurance was provided by your employer and you never received marketplace insurance in 2021.

IRS still wants me to fill out 8962 , I don't need to do it because I have 1095C from my employer. I don't know to correct
