No one can call you from the user forum. In order to prepare and file a 2018 tax return, you now have to use desktop software. Online tax preparation and e-filing for 2018 are permanently closed. Any desktop version of TurboTax has all of the forms. If you need more help with something--such as investment income or self-employment income then you might want to upgrade from Deluxe to Premier or Home and Business.
Your 2018 return must be printed, signed and mailed.

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.
