Why can't I efile this year?

Here is a great FAQ explaining E-Filing issues https://ttlc.intuit.com/replies/3302152

I don't understand this answer as an explanation

What is pre check and transmission Phase?

That is TurboTax checking over your return, and sending it.  An e-file transmission issue is when your return doesn't go through after clicking Transmit Returns Now. It's a technical problem with your computer or internet connection. If that is not the case with you, I would suggest checking out the FAQ: <a rel="nofollow" target="_blank" href="https://ttlc.intuit.com/questions/1901497-when-a-tax-return-can-t-be-e-filed-no-matter-what-you-do">https://ttlc.intuit.com/questions/1901497-when-a-tax-return-can-t-be-e-filed-no-matter-what-you-do</a>

Ok, got it. I have never had this happen before. Usually if there is an issue it lets you know before you pay for the service. Also there was an option to take the money out of the return. why can't we do that anymore?

The option to select efile is greyed out. It won't let me choose it
