Thanks for the answer. But I guess my specific question is in 2019 I just started back up teaching. I only worked, say 500 hours, but my annualized number of hours is in excess of 900. Can I take the deduction in 2019 even though the number of hours in the calendar year 2019 was less than 900, but the annualized number of hours for a full school year is in excess of 900.
Thanks
