Per IRS Instructions for Form 8917, on page 2:

Deduction extended. The tuition and fees deduction is extended for qualified tuition and fees paid in calendar years 2018, 2019, and 2020. Don’t claim the deduction for expenses paid after 2020 unless the credit is extended again. Use Form 8917 (Rev. January 2020) and these instructions for years after 2017, unless a newer revision is issued indicating it is succeeding this revision.

Periodic updating. Form 8917 will no longer be updated annually. Instead, it will only be updated when necessary. For previous years, use the applicable Form 8917 for that year.

If you can be claimed as a dependent on someone else's tax return (such as your parent's), then your qualifying educational expenses can only be used on that return. Your return would not qualify for the tuition and fees deduction.

Refer to IRS Publication 970 Tax Benefits for Education for additional information.
