How was your 2019 return prepared--in Online TurboTax or the desktop software?
If prepared in Online TurboTax, what/where is the roadblock? Are you not finding it in your account?
Log into your account, and at the Tax Home, scroll down to "Your Tax Returns & Documents." Expand that section and choose tax year 2019. Then one of the links should be to download the tax data file.
If you do that, but can't find evidence of a 2019 return there, we can tell you how to look for multiple accounts.
