Get your taxes done using TurboTax

can't say for sure but it's possible the problem is that the IRS has not finalized all the forms in your return.  Until that is done Turbotax can not update them in its app and you can't e-file.  there could be other reasons because we can't see you return. contact customer service to see if they can give you an explanation

5am-5pm Pacific Time (8-8 Eastern) Monday - Friday
