Clarity needed for paying half your own support question as a Student?

Turbotax has a question asking 'Did you provide over half of your own support with earned income during 2024'. I understand that earned income is defined as wages, salaries, tips, etc...  However, it's not clear if the money spent toward support in 2024 has to have been specifically earned in 2024?

 

My daughter worked through all through high school and a little after, saving her money for college and is now using that savings for part of what she pays for college. So, it's a mix of earned income accumulated between 2018 and 2024.
