need copy of 2023 Federal tax return How can I get it?

I filed my 2023 Federal tax in October 2024 using Turbo tax.  I sent in a partial payment of 500.00.  I just received a letter from the IRS telling me that I need to file my 2023 tax return.  How do I get the information from Turbo tax about my 2023 return?  [email address removed]
