Please refer to Table 5 on page 11 of below link for rules of claiming a dependent.
Test #4 is "The child must not have provided more than half of her own support."
Worksheet 2 on page 15 is to determine support.
In the middle section "Expenses for the Person You Supported" includes the person's total education expenses. Considering nowadays college tuition is expensive, you daughter is likely not have provided half of her own support.
If she meets all other tests from Table 5, you should be able to claim her as a dependent in your 2021 tax return.
Hope the above helps.
