I keep getting the same set of slides trying to e-file my taxes for ID confirmation...is this normal? how do I know if my taxes have been filed or not?

I don't know what you are talking about....slides?
You can check your efile status here     <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/efile-status-lookup/</a>

When you efile you get back 2 emails.  The first email only confirms the transmission.  The second email says if the IRS (or state) Accepted or Rejected your efile.

Since you are posting from a "Live" version  you can arrange for the Live help you are paying the extra fee for with your questions from  5 a.m. to 5 p.m. Pacific time Monday - Friday.
