I found this, which explains what information is needed. I don’t see anything on it about reporting that amount: NYS Higher Education Services Corporation - How to Fill Out the TAP Application 2019-20. The document explains how to report student income, and I assume parent income would be reported the same way. It asks for a line on the NY state tax return, and it indicates that there is a box to check if they received pension income. I don’t see anything about retirement contributions. Someone who knows for sure might chime in, eventually.
