If you filed with TurboTax in 2018 and do not have your 2018 return, you can sign into TurboTax with the userid that you filed with in 2018 and download your 2018 return.
Go to Tax Home and then Reports and Documents at the bottom of the page. Click on 2018 and download the 2018 pdf.
If you need to amend the 2018 return follow the directions on the screen.
You generally must file an amended return within three years of the date you filed the original return or within two years after the date you paid the tax, whichever is later.
