my tax return of 2024 didn't go thru

That would have been a 2023 tax return that you filed in 2024.    If it was not e-filed successfully, then you can file it by mail now.  E-filing is closed permanently for 2023 returns.

Print it, sign and date it in ink, and mail it.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.

"I received a confirmation email.."

When you e-file your federal return you will receive two emails from TurboTax.  The first one will say that your return was submitted.  The second email will tell you if your federal return was accepted or rejected.  If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.

First, check your e-file status to see if your return was accepted:

If the IRS accepted it, what does it say here?  

https://www.irs.gov/refunds         

  Or does your account say “Ready to Mail?”

Note:  If it says “Ready to Mail” or “Printed” that means YOU have to mail it yourself.  TurboTax does not mail your tax return for you.
