What kind of income did you enter? If you only get SS or SSDI it is not taxable and you don't have to file a return. And you can't efile with no taxable income.
Or you might be in the wrong online account? 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
