I filed my 2019 tax return through TurboTax, but it does not show up under “Documents” of my online TT account. My 2018 return does appear. How do I find my 2019 return?

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

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online.

You can also request a transcript from the IRS

When I do that it doesn't show me multiple accounts. It asks if I want to submit a request to manually get my account reviewed so I can access it. But I already know how to log in to that account. I'm very confused.
