You did not file my tax return last year Irs notified me. I need to speak with someone

TurboTax does not file your tax return.  It is up to YOU to file it by clicking on that big orange button that says "transmit my return now" and then you have to watch your email to see if your return was accepted or rejected.  If it was rejected you have to follow up, fix it and re-send it, or print, sign and mail it.

Check your account.  If it says anything other than "accepted" for your 2018 return then you did not file it; now the only way to file it is to print, sign and mail it.  If you owe tax due, then enclose a check or money order with the return, or pay directly on the IRS sitehttps://www.irs.gov/payments/direct-pay

If you are getting a refund, there is not a penalty for filing past the deadline.  If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
