You must have done something besides what you have said, perhaps inadvertently. It's not clear what you might have done.
You said you "paid all taxes owed on the return." But you also said "The Federal taxes due box at the top of the Turbotax page showed box showed a balance of zero taxes owed." If taxes were "owed on the return," then the taxes due box in TurboTax would have showed the amount owed, not zero. You must have done something after you filed to make the box show zero. Normally TurboTax continues to show the amount that was owed when the return was filed. It does not get updated when you pay the tax that you owed. On the other hand, if the taxes due box showed zero, when you filed, then you didn't owe any tax, so there was nothing that you had to pay.
Do you have a backup copy of the .tex2023 tax return file from when you filed in April? Make a copy of the filed return, and only work on the copy. Don't make changes to the original filed return.
