I have a 1095-C Heath insurance form but I can't seem to find the option to enter the form in

Right, you don't need to enter a 1095-C or 1095-B anymore.  You only enter a 1095-A.

But it seems to prevent me from filing my taxes as it is requiring me to complete a taxpayers health insurance worksheet. It's asking for a Insurance Co subscriber number which doesn't appear on the 1095-C form. 

It sounds like you are trying to enter the information from your 1095-C as if it was from the Marketplace and reported on a 1095-A Form.

 

Please look at the number of your form. 

 

If it is says 1095-C, you do not need to enter anything into TurboTax.  Please delete any sections you were trying to fill out and getting error messages on.

 

If it says 1095-A, you will make your entries as follows in the federal interview section.

1. Select Deductions & Credits 
2. Scroll down to All Tax Breaks 
3. Select Medical 
4. Select Affordable Care Act (Form 1095-A)
5. Proceed to enter your 1095-A information here.
