Retirement tax questions

If the payments are just for medical leave and you did not receive a 1099-G for it, then as long as you know the payments were only for medical leave and not paid family leave, then Amy is correct.  These payments would not be taxable.

The terminology is definitely important here.  Per Revenue Ruling 2025-04, for payments made for medical leave benefits, if the contributions are made from the employee originally, then the amount would not be included in gross income. 

Thank you for the clarification on the type of correspondence you received via email as well.
