I purchased course book in Feb 2021 for April 2021 classes. Do I claim the books on this years return since they fall in the time frame.

No.   You are asking about purchases made in 2021 and you are preparing a 2020 tax return.   Your 2021 education expenses will go on a 2021 tax return next year.

  Your 2021 education expenses may only go on a 2021 tax return next year.  There is one exception*, but your situation does not qualify. 

* If you actually paid for 1st term 2021 expenses, in 2020.
