I didn't file in 2018? Is my information still in turbotax system? What is the penalty to complete my 2018 taxes?

There may be a late filing penalty and an underpayment penalty if you owe.

The IRS applies late penalties and interest on a case-by-case basis and will send a separate bill if penalties apply.

Because the IRS has the last word on penalties, we can't calculate the exact amount if your return is late. But the info below will give you an idea of what to expect in a worst-case scenario (courtesy of IRS Tax Topic 653).

• No penalty if you're getting a tax refund.
• Late filing penalties apply if you owe taxes and didn't file your return or extension by April 15, 2019, or if you filed an extension but failed to file your return by October 15, 2019.
• The late filing penalty is 5% of the additional taxes owed amount for every month (or fraction thereof) your return is late, up to a maximum of 25%.
• If you file more than 60 days after the due date, the minimum penalty is $205 or 100% of your unpaid tax, whichever is less.
• Late payment penalties apply if you didn't pay taxes owed by April 15, 2019, regardless of whether you filed an extension or not.
• The late payment penalty is 0.5% (1/2 of 1 percent) of the additional tax owed amount for every month (or fraction thereof) the owed tax remains unpaid, up to a maximum of 25%.
• For any month(s) in which both the late-payment and late-filing penalties apply, the 0.5% late-payment penalty is waived.
• Interest (compounded daily) starts accumulating on unpaid taxes one day after the due date of the return, until the bill is fully paid off. The current interest rate is 4.18% (3% on top of the federal short-term rate of 1.18%) and is subject to change.

How do i go about filing 2018 tax return?

@ajlivefree100 Did you start a 2018 return but did not finish or file it?

If you have any changes/corrections at all to make to your 2018 return, you now have to complete it using desktop software, which you must download to a full PC or Mac  (not to a mobile device).

If you already paid for your online software you can ask customer support for a download of the desktop software.

They are available from 5 a.m. to 5 p.m. Pacific time Monday-Friday.

If you are getting a refund, there is no penalty for filing late.  If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe.  Only the IRS will calculate this—TurboTax will not calculate it.
