I am trying to complete my 2018 return after filing an extension in April. TurboTax is not letting me start now. I have used TT for the past several years. Please help

You are too late.  2018 online and e-file ended on Oct 15.   Now 2018 can only be done with TurboTax by using the CD/download software on your computer and mail the tax return to the IRS.

You can purchase the 2018 desktop version here:

You can no longer start a tax return using the TurboTax online editions after October 15, 2019 which was the last day to file a tax return with an extension without penalty if taxes were owed.  The TurboTax online editions are shutting down to make way for the 2019 online editions.

To complete a 2018 tax return using TurboTax you would need to purchase, download and install one of the 2018 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

The 2018 tax return can only be printed and mailed, it cannot be e-filed.
