Did you use Online TurboTax? A return prepared in desktop software (CD/download) will not be in an online account.
I'll assume you used Online TurboTax. Does "not showing on our account" mean you are finding no evidence at all of a 2019 return in that account, and it wants you to start one?
When you log in, is there any evidence at the Tax Home that you filed a 2019 return? Scroll down and expand the section "Your Tax Returns & Documents." Is there no evidence of a 2019 return at all in that account, and it's acting like it want you to start one? If so, then you likely have multiple accounts without realizing it and signed into the wrong one. Here's how to troubleshoot to find all your accounts:
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, you can use the tool at the link below. When using the Account Recovery tool, 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.

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.
