I need to file my 1099 for 2018 how do I do that

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

If you haven't filed a tax return for 2018, you can download the 2018 TurboTax program and prepare your return and mail it to the taxing authorities. It is too late to e-file a return from prior years, but you can mail it in. He is a link to where you can purchase the TurboTax program:  2018 TurboTax

You only have three years from the due date of a federal tax return to file for a refund, so if you are due a refund, you need to file the 2018 tax return by April 15, 2022.
