I started my 2018 taxes on the platform (I bought the Deluxe) but never filed them. How can I continue now?

Go to the following link for instructions to complete and file a 2018 tax return that you started in TurboTax Online.

How do I finish a prior-year return that I started in TurboTax Online?

Tax returns for past years cannot be e-filed. You will have to print your 2018 tax return, sign it, and file it by mail.

You now have to print and mail prior year returns.  When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS or State received the return. Mail federal and state  in separate envelopes.

You need to register a 2019 online account to access prior years
