College Decided Retirement Disbursement was Income? Financial Aid Revoked??

I’m not sure what an AGI is, sorry! I don’t believe we paid taxes on it. My former employer gave me a couple of options last year; to just stay in the retirement plan and get whatever the monthly payment was when I retired, or to take what they determined was the current value of the funds now and opt-out of the retirement plan from them altogether. We took the money and rolled it into our IRA, which was a rollover from their 401k plan when I left 10 years ago. I have a 1099R (0 taxable amount listed) from my former employer’s retirement service and a Form 5498 from Well Fargo, our advisors.
When we did out taxes this year, we did not pay any extra tax that I am aware of, nor sis our CPA have any issues with the rollover that he felt the need to tell us about. Is there someplace I can look on our tax return to be sure? I think we’ll get taxed on it when we use it?
THANKS for your help!
