Online edition..says I can’t Netfile because of the CCA 

Due to recent government updates to Capital Cost Allowance (CCA), some of your forms aren't ready for filing yet.

I have rental income but no CCA  deduction 

@Bootsfam As per our FAQ, the T776 Statement of Real Estate Rentals is locked entirely unless you are using TurboTax Desktop. Only the T777 & TP-59 specify that they are locked only when claiming CCA.
