You do not enter data into the 5329, TurboTax does, based on other entries you make.
In your case, you answer RMD questions in two places:
1. After you enter a 1099-R, it will ask you how much of this distribution was an RMD
2. After you finish entering all 1099-Rs, TurboTax will ask you whether or not you received all the RMD required.
When you answer "[name] did not receive all the RMD for 2023", the next screen should ask you how much your RMD should have been, and how much you actually took.
The next screen asks you if you would like to look into reducing your penalty. The IRS really doesn't want to hit you with a 25% penalty, so tell them that why this happened and that you are about to do a withdrawal of dollars to bring the RMD up to 100%.
