Get your taxes done using TurboTax

So after the interview upon reviewing my tax situation before filing it popped up this form the interest income worksheet and wanted me to fill in prior year distribution which I'm assuming is the counterpart to the 18K that appears in line 7A. 

But then it also wants me to fill in lines 7C - contributions made in 2023 and earlier as qell as line 7D - excess contributions in 2024... and I have no clue what to put in there. 

We made no 529 contributions last year and I'm not sure what excess contributions even mean for 2024.
