Savings bonds intended for education in 2020 not used due to Covid

Can I still exclude interest from EE Savings Bonds that were cashed with the intent to be used for my son's Education, but couldn't be used in 2020 due to Covid?   They will be used in 2021 as my son and the institution will be open.

They were left to me by my recently deceased grandmother that have long been matured.

 

Thank you.
