How do I adjust CCA amount on my T776, if I F2 on the CCA claim for the year my return is ineligible for NetFile? Thank you

You should be able to double click on the amount and change it.  

Thank you for choosing TurboTax.

Thank you for you reply, but it says the return will be ineligible for NetFile. Is this the case if i manually adjust the amount.

No, you should be able to manually adjust the amounts.
