Most users experiencing this issue have more than one TurboTax account and don't realize it. In order to access your old returns, you'll need to use the EXACT same login information (same username and password) that you used when filing those returns. I'm linking a TurboTax FAQ below that will help you see how many TT accounts you may have. When you've located the correct account, be sure to stick with that one.
How many Intuit accounts do I have with TurboTax?
