Schedule 1 of the 1040 U.S. individual income tax return for tax year 2022 has a line in part II, 24z, which says only "Other adjustments. List type and amount". The instructions for that line are similarly vague, adding only that this line should be used for adjustments "not reported anywhere else".
Obviously there must be a legal precedent for what expenses or situations you could actually use to adjust your income, but it seems to me that this line is uncomfortably vague.
What is an example of an adjustment to be made on line 24z that doesn't have a designated line elsewhere?
Is there a resource somewhere to find a list of such valid adjustments? If so, where?
