I have filed my return already and received both text and email confirmation but I keep getting email from TurboTax that I should complete my return and file.

If you know that you  filed and the return was accepted, you can disregard the marketing emails that are likely being triggered by an "old" account you still have.  Many users have multiple accounts.  As the filing deadline nears, the marketing department gets pretty active....

You can reach out to TurboTax using the link below. If you have the text and/or email confirmation about the acceptance of your tax return you should give it a day or two.
