Some forms are not ready for e-filing. If you have a Form 8829 in your return, this means this form is not ready to e-file. You will have to wait until this form has been completed by TurboTax to file.
I do not have an exact ETA for Form 8829 other than it is supposed to be ready soon. Unfortunately, you will just have to check back every couple of days to see if the form has been released for e-filing.
