I keep receiving notifications about the deadline to file my taxes but I already filed last month and received my refund. How do I let TurboTax know I paid my taxes?

My grandfather helped me and we used TurboTax to file, he used my ID and debit card so I don't understand why it's different on my phone. Is it because they're different accounts?  I just know the Irs should be aware that I paid because like I said I received my refund in the mail. It was a stimulus check. So I'm not understanding why they're telling me to file when I already did it.
