"How do I finish a prior-year return that I started in TurboTax Online?
If you started your 2016, 2017, or 2018 return in TurboTax Online but weren't able to file it before the shutdown, you can finish and paper-file it in the TurboTax download software for PC or Mac.
Start by purchasing and downloading the software and install it on your computer. If you're also filing a state, be sure to download and install the corresponding state program (PC instructions | Mac instructions).
1. Now sign in at TurboTax.com using the same login you used to prepare your prior-year return.
If you don't remember it, try account recovery. Still no luck? Then just start over in the TurboTax software you downloaded and skip the rest of these instructions.
2. Under Your tax returns & documents, select Download .tax file (not the PDF) for the prior year you want and save it to your computer.
3. Back in the CD/download software, select Find a Tax File, and then browse to the tax data file you downloaded in the previous step.
4. Select the file and click Open.
5 . You can now finish up in the software. Your return will need to be paper-filed, as e-filing prior years is no longer available."

You can only buy the download for prior years. You have to buy a separate program for each year. They only sell the last 3 years. You need a full Windows or Mac computer to install it on. Buy the download here
https://turbotax.intuit.com/personal-taxes/past-years-products/
You 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 received the return. Don’t forget state.
Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.
If you are getting a refund, there is not a penalty for filing past the deadline. You have 3 years to file for a refund. 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.
Or If you have a simple return You can fill out the blank forms for free.

Need to put my agi in my 2018 tax return cant find my return
What? What do you need the AGI for? You only need it to efile and Efiling for 2019 and prior is now closed. You have to print and mail prior year returns.
You do NOT need the 2018 AGI to mail in a 2019 return which is all you can do at this late date.
To find your returns.....
It's common to end up with multiple accounts. First LOG OUT of whatever TurboTax account you're logged into right now. Then use this TurboTax account recovery website to get a list of user ID's for an email address. Run the tool against any email addresses you may have used

You have to mail federal and state in separate envelopes because they go to different places. Get a tracking number from the post office when you mail them for proof of filing.
2018 is listed above. 2019 is the same and here are the blank IRS forms.
