It could be possible that you are in a different account. See the link below for further assistance.
I cannot access my 2018 return. It sends me directly to do 2019 return with no options in left pull down.
If your 2018 returns were prepared in Online TurboTax, and you can't find them at the Tax Home when you expand the section "Your Tax Returns & Documents" and choose the relevant tax year, then you likely have multiple accounts and signed into the wrong one. Many people end up with multiple accounts without realizing it. Here's how to troubleshoot for multiple accounts (User IDs) and regain access :
You can have up to 5 accounts that use the same email address for notification purposes. A User ID may be an email address, but it doesn't have to be. It might be only part of an email address, or it can be anything at all.
To get a list of your User IDs and recover account access, reset password, etc., you can use the tool at the link below. Try using your phone number first. After that, if necessary, then run the tool on your email address(es) you can access.
NOTE: Before running the account recovery tool below, log out of all Intuit accounts including this user forum, or you might end up in a loop. Then clear your browser Internet cache, close your browser, then reopen it, and go to the link below. You may wish to copy this link so you can paste it into the new browser session.
Account Recovery
If still no luck after running that on your phone number and email address(es) that you can access, here's another method:
Go back to the tool again, but this time leave the data field blank, and choose the small blue link that says "Try something else", and it will look you up by SSN and other parameters.
