Turbo tax messed up - did not e-file 2018 returns. Need help!

At first, I was not able to access my 2018 tax return. After giving tax audit defense permission to access on my behalf, they were told it did not exist. Then miraculously, I was able to download my 2018 returns from my turboxtax account. Weird. The issue, I have a letter from the IRS and Turbo Tax failed to e-file my 2018 returns. They never notified me that there was a problem, I have proof of my receipt that I paid the filing fees and for tax audit support. It's a nightmare to get on the phone with support. Anyone else have this issue?!
